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
22.214.171.124 - 126.96.36.199
188.8.131.52 - 184.108.40.206
220.127.116.11 - 18.104.22.168
22.214.171.124 - 126.96.36.199
188.8.131.52 - 184.108.40.206
The 220.127.116.11 - 18.104.22.168 block is not in question. This was
to NZNIC, not NZGATE, and has been well-delegated since (to Netlink,
Iprolink, Netway, Xtra and many others. There are very few (if any)
delegated to end users within this block.
1/ Route Flapping, or possible administrative decision
not to re-advertise routes less than /19 by US
(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:-
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,
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
may put users in jeopardy in the future, (b) may put them in some
now due to higher flap penalties, and (c) are an administrative
There were three possible solutions suggested:
1. Telecom's proposal - as described in the "letter" from
Telecom, describing one solution aggregating into 4
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
The meeting felt that the third option has the most promise and was
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.
