AS9433 MASSEY-AS Massey University

AS9433 (MASSEY-AS) is held by Massey University, a New Zealand university with campuses in Palmerston North, Wellington and Auckland. This is its campus autonomous system, carrying university systems and users across those sites.

What it's used for

The AS originates 8 IPv4 prefixes totalling 65,536 addresses — and every one of them is a piece of 130.123.0.0/16, a single legacy university block. The /16 is announced whole, then again as a /18, two /19s, a /22 and three /23s: the internal deaggregation of a multi-campus institution steering particular ranges rather than a network with a varied address portfolio. IPv6 is present and properly deployed, with 2001:4530::/32 announced alongside three /48s carved from it. Reverse DNS confirms the space is the university's own and even reveals its geography: wel-dp2.massey.ac.nz (Wellington), tur-nas2-cl.massey.ac.nz (Turitea, the main Palmerston North campus) and workstation-style names like it069914.massey.ac.nz. Five observed BGP neighbours against 65k addresses is firmly in institutional territory — a network that buys connectivity for its own users and sells none.

Notable

• The entire IPv4 footprint is 130.123.0.0/16; the address count is high because of that one legacy allocation, not because the network is large in any operational sense.
• rDNS hostnames are site-prefixed (wel-, tur-), reflecting Massey's distributed multi-campus structure.
• IPv6 is deployed from a /32 with per-site /48s, which is more complete IPv6 adoption than many commercial networks of comparable size manage.
