Summary

United States of America · AI-generated

education university residential us

WIU-AS is the autonomous system for Western Illinois University.

What it's used for

  • The address space carries university infrastructure and student residential networks, evidenced by reverse DNS entries like 143-43-223-254.wiu.edu and 207-246-183-254.Wetzel-south.ResNet.WIU.edu.
  • The AS announces 40960 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with an access or eyeball network serving a single institutional campus.

Notable

  • Registrants for both announced prefixes, WIU-143-43-128-17 and WIU-BLK1, are listed as Western Illinois University, matching the AS holder.
  • The address inventory consists of two distinct IPv4 blocks: 143.43.128.0/17 and 207.246.160.0/19, with no IPv6 prefixes currently announced.

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 1,783 prefixes, as published 2026-10-17. 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.
