AS14183 — UALR-ASN

AS14183 announces 1 IPv4 prefixes covering 65,536 addresses and 1 IPv6 prefixes.

About this network

A sixteen-bit block of IPv4 next to the smallest IPv6 allocation a site can be given.

What it's used for

• A university's campus network. 65,536 addresses in a single IPv4 prefix, 144.167.0.0/16, plus one IPv6 prefix, 2620:e8::/48, with one observed BGP neighbour.

Notable

• The IPv4 block carries the netname UALRNET, registered to University of Arkansas at Little Rock.
• The AS handle is UALR-ASN.
• Three addresses were queried for reverse DNS and none returned a name.
• The routing archive first saw this AS in 2008, decades after the IPv4 block was allocated.

Interesting

• The two prefixes come from opposite eras. The IPv4 range was handed out when a campus could ask for a sixteen-bit block and get one; the IPv6 range is a /48, which is what a single site receives. In addresses the second is unimaginably larger, and in intent it is far more modest.
• A /48 also means the campus went to a registry rather than taking space from its provider. That is a small act of independence: the block travels if the provider changes.
• One neighbour for an entire university, holding both prefixes. State institutions commonly reach the internet through one shared education network, and the routing table cannot tell that apart from a single commercial provider.
• The block is announced whole and nothing answers a reverse lookup, so an address here gives up no building and no department.
