Summary

University of Oklahoma

United States of America · AI-generated

education research academic

UNIV-OF-OKLAHOMA is operated by University of Oklahoma.

What it's used for

  • The address space carries academic and research traffic, evidenced by the ou.edu domain in reverse DNS records such as broadcast-129-15-127-255.fennfwsm.ou.edu.
  • The AS announces a single IPv4 prefix, 129.15.0.0/16, comprising 65536 addresses, with 0 IPv6 prefixes. With only 1 observed neighbour, the network functions as an isolated academic site rather than a transit provider.

Notable

  • The registrant University of Oklahoma matches the AS holder and the netname UOKNOR for the announced prefix.
  • The address inventory consists of a single contiguous /16 block, typical of a large institutional allocation.

Reputation

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.
