Ladies and Gentlemen, as promised, a set of minutes from the NZNOG meeting last Friday, 27th November 1998. ----------------------------------------------------------- Present Bob Grey - Clearview Peter Mott - 2Day Internet Craig Anderson - Iprolink Joe Abley - Clear Chris Wedgewood - Man about town Rowan Smith - ICONZ Tony Wicks - ICONZ Brett Telfer - Telecom Netgate Roger De Salis - Cisco/ISOCNZ Andy Linton - Netlink Don Stokes - Daedalus Consulting Subject: How to progress the NZ IP address space, to make administration and address exceptions easier, not more difficult to manage in the future. What to do about the 4 address blocks.. namely 202.27.0.0 - 202.27.255.255 202.36.0.0 - 202.37.255.255 202.49.0.0 - 202.49.255.255 202.50.0.0 - 202.50.255.255 203.96.0.0 - 203.97.255.255 The 203.96.0.0 - 203.97.255.255 block is not in question. This was delegated to NZNIC, not NZGATE, and has been well-delegated since (to Netlink, CLEAR, Iprolink, Netway, Xtra and many others. There are very few (if any) networks delegated to end users within this block. Issues arising 1/ Route Flapping, or possible administrative decision not to re-advertise routes less than /19 by US connection providers. (This is only a suggestion at this stage...) 2/ Requirement for Provider independent address space 3/ Aquisition of additional address space, by those suppliers in NZ requiring it. 4/ Mechanism of handing back address's that are no longer required or in use. 5/ An unequivocal statement that IP address space issues not be used as a commercial lever by Sales staff or other interested parties. It should be noted that all address bocks of /19 or larger are clearly large enough to be either Provider independent or Provider dependent, according to agreed terms. However, the ability to acquire a /19 block implies a scale of operations that may not suit all NZ operators. Address blocks of /25 or smaller are clearly not provider independent, for the purposes of Internet carriage in NZ. ------------------------------------------------------------------ Discussion followed about "what to do about the 4 blocks" Dominant provider within each block to advertise. Use APNIC recording mechanism to update/improve information quality, rather than create a separate recording mechanism, and attempt to keep them in sync. Discussion followed about possible creation of an NZNIC, however this was felt to be far to great a step, considering the nature of the problem. It was though that another organisation charged with "administering" IP address space was far to complex compared with the current issues open for discussion. Technical Problems arising from the current IP address regime:- 1/ Multi-homing 2/ Provider independent address space 3/ ISP not large enough to aquire a routeable block. These are more regional registry issues, rather than NZGATE issues, IMHO. The key technical issue at present is that it results in a very large number of long-prefix routes to be advertised all over the place, which (a) may put users in jeopardy in the future, (b) may put them in some jeopardy now due to higher flap penalties, and (c) are an administrative headache. There were three possible solutions suggested: 1. Telecom's proposal - as described in the "letter" from Telecom, describing one solution aggregating into 4 supernets. 2. Joe Abley's proposal - as documented 3. Andy's proposal - collapse the 4 NZGATE ranges into /19 (or larger) supernets, which will be advertised by the dominant provider in each range. The meeting felt that the third option has the most promise and was worth exploring further. The meeting gratefully received contributions from Joe Abley, a draft working paper on the NZGate Delegations. Andy Linton, a roughly correlated list of affected address's and customer names, within the 5 blocks. The following actions were agreed:- Education letter to Customers concerning "Internet Routing Best Practice" "Falling Utilisation due to increasing use of Firewalls" 2/ Document the customers in the 4 blocks Document the usage of the 4 blocks Include all address's, and ignore any issues of ownership. Use APNIC Database for Information Quality Improvement. My Thanks to all participants. Meeting closed at 2pm. -- \_ Roger De Salis Cisco Systems NZ Ltd
