AS10294 CCCD-AS

CCCD-AS belongs to the Coast Community College District, the Orange County, California district that runs Orange Coast College (Costa Mesa), Golden West College (Huntington Beach) and Coastline Community College (Fountain Valley), with district offices in Costa Mesa.

What it's used for

Campus connectivity for the three colleges and the district administration: classroom and lab networks, student services, library systems and the district's public-facing servers. The district was created in 1947 and has been a multi-campus operation since Golden West opened in 1966, so its IT estate is old enough to have been given address space in the era when a large allocation cost nothing.

Notable

This is education, and the routing is a textbook institutional pattern: RIS observes exactly one IPv4 prefix — 159.115.0.0/16, 65,536 addresses — and one BGP neighbour. A single legacy Class B announced whole, with no deaggregation and no second upstream, is what an academic institution looks like when it has held its own space since the early 1990s and reaches the internet through a single provider (in California, typically the CENIC research network that serves the community colleges).

One neighbour is decisive against every commercial reading. A hosting company with 65k addresses would multihome for resilience; a transit carrier would peer with hundreds of networks. A campus that just needs to get out to the internet buys one path.

Interesting

Reverse DNS was not observed on the two addresses sampled here, which says nothing either way — a /16 is 65,536 addresses and a two-address sample is far too thin to characterise. The routing alone carries the identification.
