AS9431 AKUNI-NZ The University of Auckland

AS9431 (AKUNI-NZ) is held by The University of Auckland, New Zealand's largest university. It is the university's campus autonomous system, carrying staff, students, halls and research systems across its Auckland sites.

What it's used for

This is a single-institution campus network and the routing view is compact and consistent with that. The AS originates just 3 IPv4 prefixes — the legacy 130.216.0.0/16 plus two small New Zealand blocks, 202.36.244.0/24 and 202.37.88.0/24 — for a total of 66,048 addresses, and 2 IPv6 prefixes (2001:df0::/48, 2404:138:4004::/48). Almost the entire address footprint is that one /16, a classful-era allocation of the sort universities received when they were among the first organisations on the internet in their country. The sampled reverse DNS resolves under auckland.ac.nz (for example sql12witprd01.uoa.auckland.ac.nz, an internally-named production server), confirming the space is used by the university itself rather than delegated to third parties. The decisive number is the neighbour count: 1. The whole network sits behind a single observed upstream, which is exactly the shape of a university connected through a national research and education network rather than buying commercial transit from several carriers.

Notable

• 130.216.0.0/16 accounts for effectively all of the announced address space — a legacy university /16.
• A single observed BGP neighbour means no peering fabric of its own; this network only consumes connectivity.
• Reverse DNS under auckland.ac.nz names internal university systems, not customer or hosting space.
