About this network

AS9432 (CANTERBURY-AS-AP) is held by the University of Canterbury in Christchurch, New Zealand. It is the university's own campus autonomous system — this is the New Zealand university, not the English city's Christ Church institution, a collision the handle alone would not resolve.

What it's used for

A campus network, and a tidy one. The AS originates 6 IPv4 prefixes totalling 41,472 addresses. Five of them are slices of a single legacy block, 132.181.0.0/16 — announced as a /18 and three /19s rather than as one aggregate, which is how a campus splits its space across faculties, residences and data-centre ranges — alongside two small New Zealand /24s, 202.36.178.0/24 and 202.36.179.0/24. On the IPv6 side it announces one large prefix, 2404:6a00::/32. Only 1 BGP neighbour is observed: the entire university reaches the internet through a single upstream, which is the standard arrangement for an institution served by a national research and education network. There is no sign of transit resale, hosting or subscriber space anywhere in the inventory.

Notable

• The sampled reverse DNS returns webapps.cce.ac.nz inside 132.181.128.0/19. cce.ac.nz is the domain of the former Christchurch College of Education, which merged into the University of Canterbury on 1 January 2007 to form its Faculty of Education. The old domain still lives inside the university's address space.
• The IPv4 footprint is essentially one legacy /16, deaggregated internally; the IPv6 footprint is a single /32.
