AS10110 MITNZ-AS-AP Manukau Institute of Technology

MITNZ-AS-AP belongs to the Manukau Institute of Technology, a public polytechnic in South Auckland, New Zealand. This is a campus network: staff, students, teaching labs and the handful of institutional services that have to face the internet.

What it's used for

Connecting MIT's Auckland campuses. The AS announces 3 IPv4 prefixes totalling 768 addresses (202.14.216.0/24, 203.176.154.0/24, 203.176.155.0/24) and no IPv6. The sampled reverse DNS lands squarely inside the institution's own academic domain: 203.176.154.133 answers as proxy4.manukau.ac.nz. A numbered web proxy is a very campus-shaped host. Schools and polytechnics have historically run outbound proxy farms so that student and staff browsing is filtered, cached and attributable, and the .ac.nz second-level domain is reserved for New Zealand tertiary institutions, so the PTR is confirmation from the naming authority as well as from the operator.

Notable

This is an education network, and the routing settles it independently of the name. Three /24s against a single observed BGP neighbour is a single-homed end site: one upstream, no customers, no peering. Neither a carrier nor a hosting provider looks like that. Traffic leaving this space is overwhelmingly campus users behind NAT and proxies, not servers.

Interesting

Because the outbound path is proxied, a large number of distinct students can appear behind one address here. Treat individual IPs in this space as shared institutional egress rather than as single users.
