AS14834 — UIS-AS

AS14834 announces 2 IPv4 prefixes covering 4,352 addresses and 1 IPv6 prefixes.

About this network

Every sampled address answered, and the two blocks use completely different naming schemes.

What it's used for

• A university campus network. 4,352 addresses across two IPv4 prefixes plus 2620:c:4000::/48 of IPv6, with one observed BGP neighbour.

Notable

• 69.67.112.0/20 carries the netname UIS-1 and 192.102.230.0/24 carries UISNA, both registered to the university with a UIS Network Administration contact.
• All six sampled addresses returned a name.
• The newer block answers dyn-69-67-116-0.uis.edu; the older one answers uis230064.uis.edu and, on one address, cspl.uis.edu.
• The AS first appeared in routing on 2007-08-30.

Interesting

• The two schemes date the blocks. The /20 marks its addresses as dynamic, the modern convention for space handed to whatever device connects. The old class-C block squashes the last two parts of the address into a single label behind the campus initials, a format from when hostnames were typed by hand and needed to be short.
• One address in that older block is named after something rather than numbered, so at least one machine there was important enough for somebody to give it a real name.
• A campus answering on every sampled address is doing the opposite of most networks in this range. Universities publish because their users run services; corporations withhold because theirs do not.
• One neighbour, and it is almost certainly the state or regional research network that every campus in the system connects through.
