AS10955 WILPATERSON

WILPATERSON is William Paterson University, a public university in Wayne, New Jersey. RIS observes 5 IPv4 prefixes covering 65,536 addresses, no IPv6, and 1 observed neighbour.

What it's used for

The announcement set is a legacy 149.151.0.0/16 plus the four /18s that tile it exactly. That is the whole of the university's address space, advertised once as an aggregate and once again in quarters. Sixty-five thousand addresses is far more than a campus of this size consumes today; it is a number that was assigned in the era when a university asked for a class B and received one. The single observed neighbour indicates the campus reaches the internet through one provider, most likely the state's research-and-education network, rather than multihoming to commercial carriers.

Notable

Announcing the covering /16 and all four /18s simultaneously is redundant from a pure reachability standpoint, since the /16 already covers everything. It is normally done to pin traffic for particular quarters of the space to particular paths, or it is a leftover from an earlier multihomed arrangement that was never cleaned up.

Interesting

No IPv6 appears in the global table for this AS. Higher education pushed IPv6 harder and earlier than almost any other sector, so a US university still running an entirely IPv4 external footprint is now the exception rather than the rule.
