NZNOG Acceptable Use Policy
by Donald Neal 14 Oct '98

14 Oct '98

NZNOG Subscribers, Below is the Acceptable Use Policy of the North American Network Operators' Group mailing list. I suspect in may be about time this list acquired such a policy, though possibly without quite so many dire warnings. It is indeed true that this list is not a cartel of any kind, and IP renumbering is clearly relevant, but it may be a good idea to have some sort of policy in place before it is needed rather than afterwards. In the absence of any feedback to this posting I intend to suggest to list subscribers the adoption of a policy bearing some resemblance to what appears below. Donald Neal NZNOG list owner/administrator/muggins ---------- Charter The NANOG mailing list is established to provide a forum for the exchange of technical information and the discussion of specific implementation issues that require cooperation among network service providers. In order to continue to provide a useful forum for discussion of relevant technical issues, the list will now be governed by the following guidelines: Acceptable Use Policy 1.Discussion will focus on Internet operational and technical issues as described in the charter of NANOG. 2.Postings of issues inconsistent with the charter are prohibited. 3.Postings to multiple mailing lists are discouraged. 4.Postings that include foul language, character assassination, and lack of respect for other participants are prohibited. 5.Blatant product marketing is unacceptable. 6.Postings of political, philosophical, and legal nature are discouraged. Individuals who violate these guidelines will be contacted personally and asked to adhere to the guidelines. If an individual persists in violating the guidelines, the convenor of NANOG, Merit Network, Inc., will take action to filter the offender's messages to the list. If groups of individuals persist in introducing topics that are outside the charter of NANOG, the convenor will send a request to the entire mailing list requesting adherence to the guidelines. If the discussion continues unabated, the convenor will take action to filter all postings on the topic. --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Hi. > I have prepared a VERY DRAFT paper in an attempt to clarify the situation > regarding IP addresses delegated historically by NZGATE, and to describe > one possible approach for bringing the current situation into line with > current policies of provider-based addressing. I must say i'm slightly confused about the rationale here. Has Telecom issued a "renumber or move to us decree"? Or is it just that they are advertising the NZGATE CIDR blocks? If they are pushing "renumber or move to us" then we should seek a legal opinion on the matter. I sincerely doubt that where a class C was issued to an NZ company with the understanding that they could move providers (and many were as this was accepted practice in 1994), that Telecom could claim any right of use whatsoever. >From the client's point of view, the restrictions suggested on the use of NZGATE addresses are not a good thing. Many of these addresses were assigned before provider based addressing was in vogue, and it's seems strange now that we should attempt to impose these restrictions and force renumbering (on moves) on networks which may wish to use NZGATE addresses in the provider independent fashion in which they were issued (a fair percentage of NZ companies connected to the Internet in NZ in 1995 had their own class C for the sole purpose that could take it with them). It is not a myth that rights or ownership _of_use_ of a Class C issued via Waikato in 1994 belongs to the company to whom it was issued. This was standard practice at the time. I'm not aware of US or European IP addresses that were, subsequent to the introduction of provider based addressing, forcibly aggregated under a single provider, nor had the conditions on which routing would be allowed revoked. The current practice of portability of NZGATE addresses is fair and fits with international practice. Any attempt by Telecom or a consortium of ISPs to limit portability is not a good thing, even if current practice now is for IP addresses to be most often issued in a non-portable fashion. To sumarise: 1) provider based addressing was not widely practiced in 1994. 2) companies obtained class C's from Waikato in that and subsequent years with the understanding that they were portable. 3) there were no distinctions between which addresses were in provider blocks and which weren't in those early years. 4) now that we have provider based addressing, it does not make sense to assume that all the old IP addresses belong to a particular provider. 5) now that we have provider based addressing, it does not make sense to impose any new limitations on IP addresses obtained earlier. Such addresses may easily require the same portability as is now required of provider blocks. 6) Neither Telecom's (alleged) ideas nor the draft's suggestions fit accepted international practice for historically assigned IP addresses. -Craig --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

I agree on a migration period as well but I think 6 months is much too long. Consider the scenario where several /22 networks change to use another provider over the 6 month period. This could result in large amounts of space being unavailable. I doubt whether APNIC would be well disposed to issue more space in this case. I'd suggest that a maximum period of two months would be a better time scale. I also believe that the 'receiving' ISP needs to make it clear to their new customer that this time scale must be adhered to. Presumably we can all agree that once we get people working from provider based blocks then the playing field is level and that renumbering is no longer such a barrier to migration. Customers need to understand that one of the costs involved in moving will be renumbering. I've currently got these networks: 203.97.128.0/17 202.37.0.0/20 202.27.40.0/21 202.49.208.0/21 202.27.64.0/22 202.27.92.0/22 202.27.104.0/22 202.36.164.0/22 202.36.192.0/22 202.37.60.0/22 202.49.72.0/22 202.27.70.0/23 202.27.78.0/23 202.27.82.0/23 202.36.32.0/23 202.36.44.0/23 202.36.162.0/23 202.36.244.0/23 202.37.32.0/23 202.37.56.0/23 202.37.72.0/23 202.27.34.0/24 202.27.68.0/24 202.27.88.0/24 202.27.100.0/24 202.27.128.0/24 202.36.29.0/24 202.36.34.0/24 202.36.46.0/24 202.36.60.0/24 202.36.70.0/24 202.36.72.0/24 202.36.76.0/24 202.36.80.0/24 202.36.114.0/24 202.36.137.0/24 202.36.141.0/24 202.36.154.0/24 202.36.157.0/24 202.36.171.0/24 202.36.173.0/24 202.36.196.0/24 202.36.198.0/24 202.36.224.0/24 202.36.229.0/24 202.36.235.0/24 202.36.239.0/24 202.36.240.0/24 202.36.251.0/24 202.36.252.0/24 202.37.23.0/24 202.37.27.0/24 202.37.52.0/24 202.37.54.0/24 202.37.78.0/24 202.37.85.0/24 202.37.112.0/24 202.37.114.0/24 202.37.166.0/24 202.37.173.0/24 202.37.235.0/24 202.49.50.0/24 202.49.84.0/24 202.49.86.0/24 202.49.140.0/24 202.49.193.0/24 202.49.194.0/24 202.49.197.0/24 202.49.206.0/24 202.50.102.0/24 202.50.137.0/24 202.50.139.0/24 202.50.164.0/24 202.50.252.0/24 --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

I'm suggesting we attempt to address historical address portability where it was rightfully assumed and that we do not attempt to force migration.

This is pretty unlikely. It would cut off major and important sections of the Internet, including most root name servers. Sprint unilaterally began filtering longer prefix routes several years ago but not those in ranges in use prior to widespread discussion of provider blocks (i.e. they have never filtered out NZGATE prefixes shorter than or equal to /24). Also, routing table growth has slowed because of the introduction of CIDR, the use of provider based addressing, and (proxy) aggregation. Routing table growth for the past three years (~1.7x) has been much slower than router CPU and memory growth and this trend is likely to continue. With it becoming increasingly easier to handle all routes, such action is now unlikely for technical reasons. The dampening used by some providers does tend to cause /24's to incur longer blocking than a /20 would as a result of flapping. But beyond this it's hard to see any potential problems with the portability of the NZGATE addresses (and many are in blocks larger than a /24 anyway). > You can be sure that many of these small routes are not carried globally > and only have connectivity because the origin of the supernet routes gets > the traffic close enough to a provider that doesn't filter. For NZGATE addresses, i do not believe this is factual. In addition to my general moaning, the draft specifically penalises many older ISPs (by making the addresses of their servers non-portable) does not address multi-homed use, and does not provide exceptions where portability is reasonable. How about policies based more roughly around these ideas: Those who obtained addresses directly from Waikato with the legitimate understanding they were portable should be treated as portable (/23 or shorter automatically qualifies). Addresses obtained from an ISP are not portable and should not be advertised by another ISP (except by agreement). No provider is allowed to advertise supernets that overlap another providers advertisements (except by agreement). -Craig --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

NZGATE addressing within NZ

Hi all, I have prepared a VERY DRAFT paper in an attempt to clarify the situation regarding IP addresses delegated historically by NZGATE, and to describe one possible approach for bringing the current situation into line with current policies of provider-based addressing. This is only one possible solution. This document is DRAFT. This document does not attempt to define policy; it is merely intended to provoke some useful discussion. >From some informal conversations on the subject it would seem that there is a widespread interest in eliminating the ambiguity that has existed on this topic, and in agreeing a strategy to allow a transition to provider- based addressing to proceed as rapidly as is practical. Please distribute this document as widely as you care to. Comments, criticism, flames and threats back to the list please, so everybody can enjoy them :) Thanks to Andy Linton and John Houlker for useful feedback and comments on earlier, even more primitive drafts. Note that any factual errors or ommisions on this history of the NZ internet are mine. The spelling mistakes are all Andy's fault, however :) Copies are available at http://www.patho.gen.nz/~jabley/nznumber.txt Joe -- Joe Abley <jabley(a)clear.co.nz> Tel +64 9 912-4065, Fax +64 9 912-5008 Network Architect, CLEAR Net http://www.clear.net.nz/ -------------------------------------------------------------------------- IP Addresses delegated from "NZGATE" in use within New Zealand 1. The problem 1.1. Overview RFC2050 documents the best current practice for address delegation for the global Internet. It imposes a framework of restrictions driven by a growing scarcity of globally-unique IP addresses and a need to summarise or aggregate routing advertisements globally to keep the Internet running reliably. The history of the Internet in New Zealand includes, at an early stage, a single domestic provider known as "NZGATE". This provider was facilitated by the University of Waikato, with international connectivity to NASA. Initially, NZGATE provided the sum total of international Internet connectivity for New Zealand. The regional authority for IP address allocation, APNIC, delegated a number of address ranges to NZGATE [3.1]. Early entrants to the Internet community in New Zealand, obtaining transit through NZGATE, were delegated address space out of these blocks according to the guidelines set down by APNIC and, indirectly, IANA. NZGATE faded out of existance in 1996 [3.2]. Since that time additional providers have added global internet transit using dedicated international circuits to their portfolio of products, including (in no particular order) Netway, IBM, CLEAR, IHUG, Telstra NZ and Voyager. Most of these participants have obtained address delegations directly from an appropriate regional registry, as they are diversely connected and don't favour a single provider for "default routing". Newly-connected customers of these transit providers (be they end users or resellers, i.e. ISPs) have been delegated address space by their providers, from the blocks delegated to those providers from APNIC, according to RFC2050. If these customers change providers, they are obliged to return the address delegations to their old provider, and obtain corresponding new ranges from their new provider. 1.2. Issues 1.2.1. Stability and RFC2050 It is extremely important from a technical standpoint that provider-based aggregation and delegation is adhered to for all customers who do not meet the criteria for operating under addresses delegated directly from APNIC. 1.2.2. Impact on end-users Renumbering can be an expensive exercise for some end users, especially those whose networks have evolved for some years. In the early days of the Internet in New Zealand, provider-based addressing was not part of the network design. Provider-based addressing first came under discussion as a solution to problems of scale, and only gradually moved from being a radical departure from good practice to an accepted reality. The evolutionary nature of this change was good in the sense that the impact could be somewhat tuned to the timeline of the allocations and expectations, but was bad in the sense that the moving situation added to the complexity and uncertainty. Many established end-user networks were built without the expectation that the IP addresses delegated to them were tied to a particular provider. Now that provider-based addressing is widely recognised as best current practice and is required by the regional registries, the requirement to renumber upon changing provider is still widely misunderstood. It is worth noting that there was no way that NZGATE (or any other ISP at the time) could solve all the issues of address portability raised by the addressing policy changes sweeping across the internet. Many NZGATE-numbered end-users may already have changed providers without renumbering, reinforcing the unfortunate myth that the NZGATE addresses they are using are still inherently portable, and "owned" by them. Although some providers now include clauses in their customer contracts underlining the point that addresses delegated as part of service delivery must be returned at the end of the contract, this is by no means universal, and the myth of "customer-owned IP addresses" lives on. It is imperative going forward that the concept of provider-based addressing and the non-portability of most network numbers is widely publicised amongst end-users. 1.2.3. Impact on national providers For ISPs that obtain global transit through other providers, and who have not arranged address delegations directly from APNIC, renumbering may be just as onerous as for end-users. Additionally national providers may supply end-users for whom renumbering is expensive, and the associated inconvenience mentioned in [1.2.2] is cumulative. 1.2.4. Competitive advantage There has been a misconception within the NZ Internet community that Netway communications (and, latterly, NetGate/Telecom NZ) assumed the NZGATE role by providing connectivity to the Waikato network in early 1996, and by virtue of this fact the addresses delegated by APNIC to NZGATE are now, by proxy, effectively delegated to Telecom NZ. This does not appear to be a view held by others involved in the "transition" [3.2]. More accurately, for a time Netway was the sole provider to NZGATE, and hence also to all downstream networks of NZGATE. This situation soon changed, with other providers bringing international transit to NZGATE subscribers, and NZGATE slowly faded out of existance leaving end-user networks direct customers of the new international providers. It is not at all obvious that any single provider can lay legitimate claim to operational responsibility of the NZGATE blocks. The effective use of these addresses as "portable" between providers over the past few years is not compatible with a delegation model whereby it is acceptable for NetGate customer networks to use them, but not acceptable for a customer of another provider. In effect, an expectation has been raised by Telecom NZ that customers who have been happily numbered under NZGATE addresses (and have used a variety of ISPs for some time) are now faced with a choice of (a) renumber, or (b) change providers to NetGate/Xtra. Due to the operational cost of renumbering, this gives Telecom NZ competitive advantages over other ISPs based on the contentious belief that Telecom has assumed operational responsibility for the NZGATE address blocks. Many address ranges delegated from the NZGATE blocks, although well documented at the time, have since been unofficially "transferred" to other operators, or are not currently in use. Hence documentation of the current state of NZGATE delegations is out-of-date. The operational responsibility for the NZGATE address blocks, when coupled with a lack of documentation for past delegations is, in fact, a hindrance to Telecom NZ, as it makes strict compliance with APNIC policy for the delegation of additional address blocks far more difficult. 1.3. Unified approach It is in the interests of all providers within NZ that a solution to the problems outlined in this document be found. It is also important that no single provider is seen to be responsible for what may be seen by end-users as restrictions, or inconvenient changes of policy. By taking a unified approach to the problem with a policy document agreed by the majority of New Zealand providers, the risk of confusion is minimised and the chances of productive user education are increased. It is proposed that the unified policy be agreed as an operational exercise within the provider community, by the usual open discussion within the NZNOG forum. 2. One possible solution 2.1. Overview The proposed solution attempts to minimise the risks discussed in [1.2], whilst providing a clear migration path towards full provider-based addressing within New Zealand. 2.2. Rationalisation of historical NZGATE delegations A list should be generated (and published) documenting subnets of the NZGATE blocks [3.1] which are in use at some agreed time. All blocks being so-used should be documented. If the sections of the NZGATE blocks in use by Telecom/NetGate/Xtra infrastructure (and not by end-users of Telecom/NetGate/Xtra) are conveniently contiguous, it will make sense to re-designate those blocks as delegated to Telecom rather than "NZGATE". On the other hand, if it transpires that the NZGATE blocks are overly fragmented to make this impractical, Telecom should approach APNIC for a further, distinct address delegation. 2.3. Administrative control of NZGATE blocks returned to APNIC All NZGATE-derived subnets not in use at the agreed time should be returned to APNIC for administration. No further delegations from the NZGATE blocks should be permitted by any NZ provider. To enforce this, providers in NZ may apply route filters to prevent the use of non-approved NZGATE address ranges. 2.4. Forced renumbering No end-user network using NZGATE subnets should be obliged to renumber as part of the normal course of their operation (but see [2.5] and [2.6]). 2.5. Process for extending address space delegations Any end-user network which needs additional addresses due to growth should be obliged to renumber with provider-based addressing in order to obtain their larger address range. The released NZGATE addresses will be returned to APNIC by the ISP. 2.6. Process for managing ISP-hopping by end-user networks Any end-user network that uses NZGATE numbers and decides to change ISPs must renumber using provider-based addressing provided by the new ISP. The released NZGATE addresses will be returned to APNIC by the former ISP. 2.7. Process for managing ISP-hopping by national providers Any national provider that uses NZGATE numbers and decides to change global transit providers must renumber its own infrastructure using provider-based addressing provided by the new global transit provider. Customers of the national provider who use NZGATE numbers will not be required to renumber (but see [2.5], [2.6]). 3. References 3.1. Netblocks delegated historically to NZGATE-NZ The addresses concerned have all been delegated from within the NZGATE-NZ networks as recorded at APNIC, which are described as: netname: NZGATE-NZ descr: NZ Gate National Service Provider descr: Component of University Of Waikato descr: New Zeland The netblocks currently assigned to NZGATE-NZ are: inetnum: 202.27.0.0 - 202.27.255.255 inetnum: 202.49.0.0 - 202.49.255.255 inetnum: 202.50.0.0 - 202.50.255.255 inetnum: 202.36.0.0 - 202.37.255.255 inetnum: 203.96.0.0 - 203.97.255.255 The netblock 203.96.0.0 - 203.97.255.255 is perhaps erroneously attributed to NZGATE-NZ here - in fact, this block was delegated to an APNIC confederate member, NZNIC, operated by the University of Waikato.

Telecom (i.e., Netway) did not "take over" NZGate, but nor did NZGate instantly "cease to exist" (such a step was simply not possible). Netway did become NZGate's supplier for a significant period while NZGate gradually reduced out of existence (I believe this started in January 1996). At the time NZGate shut down its international links this was phased with the introduction of commercial providers offering international capacity at the NZIX, but it was a complex transition with Telecom and Clear only slowly coming to grips with international IP services, and NZGate clients only slowly working out what they should do. The NZGate international circuit contracts came up to expiry in January 1996 (and we were in no position to renew for a further 12 months) and the NASA "PACCOM" access was supposed to cease in February 1996 (in the event it didn't, but we could not count on further access to the NASA FIX-WEST gateway beyond that date). We were not in a position, however, to disperse all the NZGate customers to direct supply from the newly establishing commercial suppliers (Clear made a late start with limited bandwidth, pricing was still under negotiation, all this was proving harder for the new entrants than they expected). Indeed we were asked to keep NZGate going to give our clients more time to sort out alternatives. As a result NZGate continued as a reseller, i.e., an intermediate IP provider, and we bought our international supply from Netway (our only option at the time). The University network "Kawaihiko" ceased being a customer of "NZGate" and moved to buy directly (also from Netway). As you know, somewhat later Kawaihiko took the considerably more complicated step of "multi-homing", buying from Netway and Clear in parallel (and later again, also from Telstra). In this way Netway "inherited" the NZGate address blocks as they were at that time - since they became suppliers to the remains of NZGate, and Kawaihiko (and they later picked up the then "CRINET" and AgNet as well). I would be interested in your comments, I haven't seen the Herald article, but it does sound like there are sites that don't yet know the implications of moving provider. In terms of the old blocks of former NZGate addresses it could indeed be most useful to get special treatment from the APNIC to allow greater flexibility in on-going devolution of the original NZGate group. As things stand Telecom have no option but to comply with APNIC requirements on efficient use of address space (this does not apply to the "NZNIC confederation" space that Waikato allocated to ISPs - in an attempt to assist portability - i.e., 203.96.0.0/15, which is entirely independent. Whether or not the APNIC would agree to a special approach here, it seems there may be existing customers of Telecom (or of ISPs using Telecom) who aren't yet aware of the portability issues. If not, perhaps some publicity drive out of Telecom and/or perhaps NZNOG contacts could spread the word. I asked Jim Higgens if ISOCNZ has good contacts to spread information to ISPs but I gather that (especially given the demise of ISPANZ) NZNOG may be the best shot. John 4.

Route servers on Citylink (WIX)
by Simon Blake 07 Oct '98

07 Oct '98

Hi Folks For the last couple of months I've had a linux box running the MRT route daemon as an experimental BGP route server, with links between a few organisations on Citylink who were happy to participate in a trial. The main aim of the experiment was to consider ways that Citylink connected organisations with BGP capable routers but without AS numbers might exchange routing data, so that they can send data directly between each other, without having to go through one (or several) ISP routers. As a rudimentary route server, MRT seems to work really well (it lacks some of the RIPE tools of the Merit RA, but on the other hand, it compiles under Linux :-). We ended up setting up MRT to peer with the organisations who had AS numbers, and then setup all the other routers in AS number 65502 (chosen at random) as static routes within MRT, and redistributed them into BGP. Turn off synchronisation on the routers in AS65502, and everything seemed to work as advertised (this is speaking from memory, I haven't looked at it for about 6 weeks). Citylink is now at the stage where we've got customers pestering us to incorporate them into the system, and a management itchy keen to take some money off of these people. So I guess what I'm after from the list is some opinions on whether this is a good idea, and I'm on the right track. Obviously, for this to be more than a toy I need the ISP's on Citylink to participate in such an exchange, so recommendations on making it easier for them to be involved are welcome.
