AS11394 CITYOFRICHARDSON-AS

CITYOFRICHARDSON-AS is the municipal network of the City of Richardson, Texas, a Dallas-area suburb. It is a small, self-contained government network: three /24s, 768 addresses, and a single observed BGP neighbour.

What it's used for

City-government IT. Richardson holds and announces its own address space rather than sitting entirely on a provider's, which is common for a mid-sized US city that runs public-safety dispatch, utility billing, traffic systems and a public-facing web presence and wants portable addressing across upstream contracts. The reverse DNS on the sampled addresses lands under cor.gov and cor.net (cor = City Of Richardson), naming a Barracuda security appliance and a test host: first-party municipal infrastructure, not customer or hosting space.

Notable

All three prefixes (198.17.195.0/24, 199.233.119.0/24, 192.231.41.0/24) are registered in ARIN directly to the City of Richardson, under three separate network handles. Registrant, announcer and reverse-DNS zone all agree, which is the cleanest form of evidence that this is a genuine end-site operator and not space parked or leased under a municipal name.

The single observed neighbour is the giveaway on role: the AS takes transit from one upstream and provides none. It exists for provider independence and multihoming headroom, not to move anyone else's traffic. A wholesale carrier of any size would show tens to hundreds of peers.

Interesting

Richardson is the historic heart of the "Telecom Corridor" north of Dallas, so the city's own network being this modest is a pleasant contrast with the fibre density around it.
