Summary

United States · AI-generated

education research infrastructure

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,779 prefixes, as published 2026-10-22. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
