AS11863 PLU

PLU is Pacific Lutheran University, a private liberal-arts university in Parkland, Washington, just outside Tacoma. It runs a single-campus network on its own AS.

What it's used for

Campus connectivity. RIS observes one announced prefix, 152.117.0.0/20 (4,096 addresses), no IPv6, and two observed BGP neighbours. That is the classic shape of a small university: one contiguous block covering staff, student and lab space, and a pair of upstreams for redundancy rather than the wide peering fabric a transit network would show.

ARIN registers 152.117.0.0/20 as PLU to Pacific Lutheran University, so the announcer and the registrant are the same institution and the prefix-registrant check clears. Nothing in the inventory is scattered across RIRs, registered to unrelated parties, or otherwise suggestive of space being flown for someone else.

Notable

PLU is a three-letter handle that could plausibly belong to several things, and here it resolves to the obvious one, confirmed by the registrant org on the block itself rather than by the handle alone. That check matters in this AS range, where short handles frequently name something other than the institution they evoke.

Two addresses were sampled for reverse DNS and neither answered. Two out of 4,096 is a sample, not a finding, so no claim is made about the university's rDNS delegation in either direction.
