Hi. > I took another look at this data and I see some differences. I see a lot too :-( Turns out my program for doing joins on CIDR blocks had a bug and that the inetnum's in the APNIC database couldn't always be rewritten as a single CIDR block (e.g. 202.36.149.0-202.36.153.255) which i had assumed... However, i guess after the beers on Friday this is no longer needed :-) -Craig --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Hi, Someone is using 203.98.24.1 (pcombo.co.nz) to relay mail to the CLEAR Net MX hosts. Since 00:16:57 this morning there have been several hundreds of thousands of attempts to deliver mail to CLEAR Net, which have been blocked at CLEAR Net since the senders' domain is not real.

Hi. Here is a table of OSPF advertisements at NZIX and BGP announcements in Europe, the AS number for the corresponding BGP advertisment as seen in Europe, and the first descr line in the APNIC database. It may give a good indication of the current use of NZGATE (and NZNIC) addresses. If the /16's are removed, would this represent (say within 20%) of the address space in use today? -Craig ------------------------------------------------------------------------------ 202.27.0.0/16 4648 NZ Gate National Service Provider 202.27.100.0/22 4768 Bell South Auckland 202.27.103.0/24 4768 NZ Gate National Service Provider 202.27.104.0/22 7714 Nelson City Council 202.27.113.0/24 4648 Combines Rural Traders, Otago 202.27.115.0/24 4768 Bay of Plenty Polytech 202.27.119.0/24 4763 CEDENCO FOODS LTD 202.27.120.0/22 4768 Asia Pacific World Travel Ltd 202.27.120.0/24 4768 NZ Gate National Service Provider 202.27.128.0/24 7714 NZ Gate National Service Provider 202.27.132.0/24 4648 Tip Top Ice Cream Company Ltd 202.27.138.0/24 4648 Telecom Mobile Communications 202.27.140.0/24 4648 NZ Gate National Service Provider 202.27.146.0/24 4648 NZ Gate National Service Provider 202.27.148.0/24 4648 NZ Gate National Service Provider 202.27.149.0/24 4648 NZ Gate National Service Provider 202.27.150.0/24 4648 Telecom Directories NZ Limited 202.27.151.0/24 4648 Telecom Directories Limited 202.27.156.0/22 4648 Telecom Online Service 202.27.16.0/20 4657 Singapore Press Holdings Ltd./Information Technology Division 202.27.160.0/24 4648 The Great Elk Company Limited 202.27.169.0/24 4648 Netway Communications Ltd 202.27.176.0/21 4648 Telecom Online Service 202.27.184.0/23 4648 Telecom Online Service 202.27.186.0/23 4648 NetAccess 202.27.192.0/24 4648 Madison Systems Limited 202.27.193.0/24 4648 IDG Communications Limited 202.27.194.0/24 4648 Hybrid Systems Limited 202.27.195.0/24 4648 New Zealand Dairy Foods 202.27.197.0/24 4763 New Zealand Microcomputer Club Inc 202.27.198.0/24 4763 Hypercom Communication Technologies Ltd 202.27.200.0/24 4648 NZ Gate National Service Provider 202.27.201.0/24 4648 NZ Gate National Service Provider 202.27.203.0/24 4648 NZ Gate National Service Provider 202.27.204.0/24 4648 NZNET Internet Services Ltd. 202.27.208.0/24 4648 Advanced Digital Business Solutions 202.27.209.0/24 4648 Telecom Business Systems 202.27.210.0/24 4763 NZ Gate National Service Provider 202.27.211.0/24 4763 Phillips Fox 202.27.212.0/24 4763 Kings College Auckland 202.27.213.0/24 4763 Pharos System Ltd 202.27.214.0/24 4763 MaC Consultants 202.27.215.0/24 4763 Citadel Computer Systems Ltd 202.27.216.0/24 4763 Building Information 202.27.217.0/24 4763 Datasure Management Systems 202.27.218.0/24 4763 NZ Gate National Service Provider 202.27.219.0/24 4763 I-Sys Training Services 202.27.222.0/24 4763 NZ Gate National Service Provider 202.27.223.0/24 4763 Show-Off New Zealand Limited 202.27.232.0/24 4648 NZ Gate National Service Provider 202.27.234.0/24 4648 Wickliffe Press Limited 202.27.236.0/24 4763 Howick Intermediate School 202.27.240.0/24 4648 NZ Gate National Service Provider 202.27.241.0/24 4648 NZ Gate National Service Provider 202.27.242.0/24 4648 NZ Gate National Service Provider 202.27.243.0/24 4648 NZ Gate National Service Provider 202.27.244.0/24 4648 NZ Gate National Service Provider 202.27.247.0/24 4763 Gisborne District Council 202.27.248.0/24 4763 Netbyte Internet Service Provider 202.27.250.0/24 4763 W.

Yes, they do, and yes, they are. At least, within the same local area. Just to be awkward, consider a cell phone number. The cell networks are set up to divorce indentity from locality. Landline telephone networks are less well set up, but still capable. In fact the situation is much as for IP---the exchanges have to maintain lookup tables that say "send *this* number *there*", rather than using rule based routing. Where IP and the telephone system differ is that this cost is incurred only at call setup (which is why TCNZ's current policy is iniquitous) whereas IP routes individual packets. But that's what caches are for. Back to the subject at hand. Back when we set up the VUW network, we had about 12 (from memory) machines set up using an invalid IP network 'plucked from the air'. This was before the private address ranges. When we got our class B (where we argued that although we did not have more than 254 machines, we would some day. Try that now :-). I recall the pain in moving. For only 12 machines. When I got here I found (invalid) IP addresses hard coded in all sorts of unfortunate places. Most had been set up by 3rd party equipment suppliers. Some were due to lazy (and IP-unaware) programmers. The point I am making is: Do NOT underestimate the pain caused by IP renumbering. Now that everyone and his dog is using IP, all sorts of pieces of equipment you might not expect have addresses buried deep with in them, and 18 mo down the track this fact is unknown to the current keepers of the key. -- Michael Newbery Technology Manager Saturn Communications Tel: +64-4-915 5102 Mobile:021-642 957 Fax:+64-4-939 5100 --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Hi Robert, Thanks for the excellent perspective on this issue. I'll only make a few comments. > 3. New entrants should not be disadvantaged (as they would be if we have one > set of rules for NZGATE addresses) and should also be able to obtain > provider independent addresses on terms no less attractive than existing > operators enjoy. For entrants who expect to need a reasonable amount of address space, there is little difference. The situation for those needing less is, unfortunately, difficult because small blocks of newly obtained addresses are unlikely to be routable. However, new entrants may be able to use NATs or otherwise build their systems to allow easy renumbering. The main problem for existing users is that changing can be difficult, expensive, and not commercially viable because few had anticipated a need to ever have to renumber (and the systems to make this easy were not available then). > 4. Incentives to corporates in particular to relinquish unused addresses This is an excellent idea. Perhaps all the incentives are already there (improved security, portability, future proofing, shorter outages from route flapping, etc). Perhaps we put together a readable document on the subject and distribute it widely. Providing incentives is certainly a much better approach than trying to coerce people into migrating -- and maybe we could get corporates to migrate without moving (resulting in more migration). > One of the elements missing here in NZ is the idea of a Local Internet > Registry, see http://www.ripe.net/docs/ripe-159.html (which is kind of what > I thought NZGATE was). I think lots of others did too, including APNIC. -Craig --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Hi. > Who do you propose will pay the end users for the pain and real costs > involved? The ISPs have the easy part of this renumbering. I don't see > people renumbering because it's the right thing to do. They'll do it > because they have to e.g. when they move ISP. But if they have a /24 they don't have to. What this group is attempting to do is impose costs on the end users only if they try to move ISPs. It's a great way to lock up your clients. There is no technical reason to make users renumber when they move (just as there is no strong reason to make everyone move for the sake of moving). Getting everyone to migrate seems to be a goal, but yet by making users renumber only when they move, you will slow movement and thus migration. Importantly, the current proposal is not workable. The first client whose renumbering exercise is expensive will likely seek an injuction against any provider attempting to enforce these ideas. The balance of convenience would favor the end user and not the provider (who will suffer zero or no loss or convenience as a result of the end user not renumbering). In the case of an ISP, web hosting company, or business which depends on the Internet (and that's a good percentage of them now), not changing providers may not be a viable option. By opening the door with an N month grace period you are only showing everyone that it's technically possible but that you don't want to do it for commercial reasons. Restrictions on portability have never been _introduced_ anywhere else for _historical_ IP addresses. Half the root name servers are running on /24s -- every wonder why that is? I see no real benefit here -- we will still have ISPs moving these addresses around for years to come (the proposal rightly allows for that) -- what reason makes routes for ISPs look any different than routes for end users? How about we just agree to ask clients with NZGATE number to renumber on moves (we have a form/statement we all agree to give them), but eliminate any requirement to renumber)? -Craig --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Clearly this subject has provoked some very considered discussion on the subject of address portability. For those interested RIPE-127 (http://www.ripe.net/docs/ripe-127.html) provides a useful and lucid dissertation on the subject and offers a number of sensible recommendations. To selectively quote "All early Internet address space assignments were provider independent. Many assignments made by ISPs are also formally provider independent because they lack the clear prior understanding between ISP and customer that the assignment will end with the termination of the service." On the historical side regarding NZGATE I personally believe this is the key issue, i.e. unless you were told the space was not portable then it is. This however begs the question of how best to organise for the future. We are not an ISP in the accepted sense as we do not offer connectivity except as part of an overall package. We are however a significant user of IP addresses for web and mail servers. Joe's possible solution and the discussion so far causes us some concern. Having recently been through the process of re-numbering and implementing NAT it proved a major undertaking and one I would hesitate to repeat. We made a number of errors resulting in outages for our clients and irritation to our suppliers and I am at a loss to see how these could have been avoided. Hopefully with NAT now in place we would make it a little easier however the number and scope of DNS changes, firewall changes, authentication changes and the fact that these must occur in one 'hit' makes it commercially pretty unacceptable. With today's firewalls/proxy servers there should be no issue for even large corporates to renumber over time, given incentive to do so. IPv6 should give this if no other reason. Smaller providers however are faced with significant problems in re-numbering which although they may seem small time are in fact relatively expensive and difficult for such an operator to overcome. We now have an example where one of our clients has been enticed by the offer of a /24 by another ISP with NZGATE addresses to burn, something we are unable to provide. I have to say that I consider this sort of behaviour seriously unethical. For me, key elements of a solution are: 1. Access providers should not be able to hold downstream operators to ransom by withholding IP addresses and forcing such users to renumber if they move. 2. The solution should offer all existing ISP players long term access to the provider independent IP addresses they need to do business. In other words a level playing field. 3. New entrants should not be disadvantaged (as they would be if we have one set of rules for NZGATE addresses) and should also be able to obtain provider independent addresses on terms no less attractive than existing operators enjoy. 4. Incentives to corporates in particular to relinquish unused addresses One of the elements missing here in NZ is the idea of a Local Internet Registry, see http://www.ripe.net/docs/ripe-159.html (which is kind of what I thought NZGATE was). To quote again "Local IRs are typically operated by ISPs and serve the customers of those ISPs as well as the customers of smaller ISPs who are connected to the rest of the Internet through the larger ISP." Seems to me that a Local IR might be really useful. If I can contribute a beer sounds like an excellent scheme.
