AS14209 — UT-CHATTANOOGA

AS14209 announces 3 IPv4 prefixes covering 33,280 addresses and 1 IPv6 prefixes.

About this network

A block whose netname says internal answers publicly, and the one block that is not the university's answers under a local electric utility's domain.

What it's used for

• A university campus network. 33,280 addresses across three IPv4 prefixes plus one IPv6 prefix, 2620:ed:c000::/48, with two observed BGP neighbours.

Notable

• 150.182.128.0/17 carries the netname UTC and 192.30.208.0/24 carries UTC-INTERNAL, both registered to University of Tennessee at Chattanooga with a Technical Support contact.
• The lookup for 74.205.132.0/24 failed, so its registration is unknown.
• Every one of the nine sampled addresses returned a name. The university's two blocks answer as 150-182-160-0.dynamic.utc.edu and 192-30-208-64.dynamic.utc.edu.
• The third block answers as static-host-74-205-132-64.epbinternet.com.

Interesting

• A netname reading UTC-INTERNAL on a block that is publicly announced and publicly named is a label describing intent at registration time, not reachability now. Registry text ages; routing does not.
• Both university blocks are called dynamic regardless of size, so the zone is generated wholesale rather than reflecting how any given address is assigned. The third calls itself static-host, which is the same shortcut taken from the opposite direction.
• That third domain belongs to a municipal electric utility that also sells internet service. A campus taking a second upstream from the local power company shows up here as a /24 sitting inside somebody else's naming scheme.
• Two neighbours on a campus of this size is the usual university shape: a shared research network first, a commercial path second for everything the research network will not carry.
