IP Addressing
by Arron Scott 21 Apr '98

21 Apr '98

OK, so to continue with my discussion, let's talk about IP addressing. Known: All RFC's and most International Internet access providers encourage the use of hierarchical CIDR based IP addressing. This is for two main objectives, save the Net from address exhaustion and the curse of IPv6, and to ensure the core routers have enough memory to be able to continue forwarding packets. When a downstream customer moves from one provider to another, and his class C network goes with him, his network is now added to the routing table as a black hole, which increases memory utilisation in the core, one or two of these is fine, but hundreds is not very acceptable to the upstream providers. Unknown: - If a customer does move providers how long should they have before the must renumber into their new providers space ? - What size block of a providers space might be considered portable ? - What steps can be taken to recover the address space if the customer does not relinquish it ?

Things To Do - Arron Scott
by Donald Neal 19 Apr '98

19 Apr '98

NZNOG People, This message was sent to the list just over two months ago by Arron Scott. I'm sending it again (without asking him first) because of the number of people to have joined the list since then. - Donald Neal - - - - - - Hi Donald, sorry, busy as ever. Yes I am getting these. As for some things I would like to see happen: First of all, I think it's important we know who's subscribed to this list, for the sake of fairness, so can we be kept abrest of changes. I think it's impportant that we communicate with all of the main providers of Internet in New Zealand, and am keen particularly to see IBM, Compuserve, and IHUG invited. No point in being secretive. What should we accomplish, IMHO: IP addressing consensus. We have to have a firm and agreed policy as to what happens with portability of address space. Domestic peering strategy, eg. progressing the AMX. Communication lines, particularly contact agreements for movement of customers from supplier to supplier or faults due to incorrect advertisements. Should Telecom be able to call Telstra staff in the middle of the weekend to get them to stop advertising a customer ? If so how ? If not what do we tell our customers ? What should we not do, IMHO: We are not a regulatory body of any kind, this should be a communication forum only allowing us to discuss and action topics as above. Contractual or formal Agreements should be made outside of this group.

Changes in OSPF advertisements made from CLEAR over NZIX
by Joe Abley 13 Apr '98

13 Apr '98

Hi all, CLEAR currently advertises connectivity to its internal networks and those of its customers across NZIX. The external routes which are currently redistributed into the exchange OSPF process include a large number of long-prefix routes, such as /30s and /28s; in the interests of being tidy (and consistent with CLEAR's BGP advertisements) I would like to summarise most, if not all, of these advertisements by distributing supernet routes. For example, instead of >100 individual routes within CLEAR's 203.97.0.0/17 CIDR block, I would like to advertise a single 203.97.0.0/17 supernet route. Total number of supernets to be announced would be around 30. This approach presupposes that (a) all equipment connected to the exchange can handle supernetting, and (b) that the loss of specificity in the domestic routes for CLEAR's networks is not going to cause problems with conflicting BGP routes picked up from other global transit providers. There may also be route filters which need to be updated. In the interests of maintaining connectivity within NZ, I would be grateful if you could take the time to consider whether the changes broadly outlined above will affect the way that your network treats routes to CLEAR across NZIX. If you could give me some feedback (no matter how general) this week, it would be most appreciated. I have attempted to distribute this message to as many exchange partners as I have been able to find e-mail addresses for - please feel free to forward copies on to other interested parties. As an aside, the NZNOG list operated (facilitated?) by Donald Neal at Waikato Univeristy would provide a good forum for these kinds of announcements in future. If you haven't already, you might consider subscribing - send mail to majordomo(a)list.waikato.ac.nz with the line "subscribe nznog" in the message body (Donald please correct me if I've stuffed that up :) Regards, 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/ --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Publicising this list
by Joe Abley 29 Mar '98

29 Mar '98

Hi all, This would seem to be a sensible forum to get some discussion running on peering within NZ, either across the NZIX switch, across WIX or via bilateral peer-to-peer circuits. It might also be a good place to gauge enthusiasm for a "BGP only" policy at NZIX, with or without a local route server. Might I suggest that we pursue some low-key publicity of this list to get network administrators from Netlink, IHUG, Iconz, Pronet, Actrix, Voyager, Xtra(?), etc, etc involved and speaking about these issues? >From the rumblings I have been hearing critical mass for the eradication of OSPF on the NZIX switch should be a fairly straightforward first objective, and recent domestic peering "upsets" would have been easier to track down with a list full of network people.

OK, in reponse to Roger Hicks' posting below I've added the people named in the headers of his message to a mailing list I've called nznog. The address to send mail to is nznog(a)list.waikato.ac.nz. There's a fair amount else the Majordomo and related software on that box can do, but there doesn't seem a lot of point to explaining that just yet. Could people receiving this please reply to me verifying that thye have seen it?
