Summary

University of Warwick

United Kingdom · AI-generated

education research campus

The AS handle UOW-AS is held by University of Warwick.

What it's used for

  • The address space carries university infrastructure, evidenced by netname UNI-WARWICK-LINR and reverse DNS entries such as gw-137-205-191-0.csv.warwick.ac.uk and hosts-10-4-0-0.warwickpiazza.net.
  • The network announces 65792 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a single-site campus network rather than a transit or multi-site access provider.
  • Traffic consists of academic research, administrative services, and student/staff connectivity within the university's physical estate.

Notable

  • Registrants for the primary prefix 137.205.0.0/16 align with the announcer, listing University of Warwick and its network team.
  • The inventory comprises one large /16 block and one /24 block, typical of a single institutional allocation.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
