Well Sprint only accepts /24 in historical ranges (to
which the NZGATE
addresses belong). Current practice seems to be to filter at the
minimum allocation size for the /8's. For all new and assignments in the
recent past this seems to be /19 (from all registries), for older addresses
this was /24.
This was my understanding as well -- for NZ, pretty much anything down
to a class C in 192/8 or 202/8 is basically portable. Experience has
show that to be true in practice as well -- I certainly haven't heard of
anyone having to renumber such an address for technical reasons.
The issue seems to come down to what exactly the conditions the NZGATE
blocks had imposed on them. I don't recall John Houlker or his
underlings ever communicating to me or anyone else that the addresses
obtained through NZGATE were anything but portable; rather, the position
stated quite explicitly to me was that NZGATE was simply front-ending
normal APNIC requests for no other reason than that it meant that the
NZGATE folks knew what was going on, and therefore could take steps to
get the new address space routed as soon as it was allocated.
No change in that arrangement was ever communicated to me while I was at
NetLink, at least until NetGate was split off, by which time NetLink
(along with most ISPs) had its own /18 block in 203 (later extended to
/17) via John H's confederation.
I'd therefore contend that the IP addresses assigned to NetLink by
NZGATE "belong" to no-one other than the original registrant. (NetLink
policy at the time was to apply for numbers on behalf of the customer;
the numbers were therefore the "property" of the customer, not NetLink,
and not NZGATE.) Obviously, I can't speak for anyone else, but I would
have thought that the same applied to any address space obtained from
NZGATE prior to its handing over to Telecom in early 1996.
