Summary

Northern Kentucky University

United States of America · AI-generated

education university business

The AS handle NKU-AS1 is held by Northern Kentucky University.

What it's used for

  • The space carries university infrastructure, evidenced by the registrant Northern Kentucky University and netnames NKR and NET-74-143-180-0-1.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 3 observed neighbours, a ratio consistent with a small institutional network rather than a transit provider.

Notable

  • Registrants align with the announcer, listing NKR and Northern Kentucky University for the respective prefixes.
  • The address inventory consists of two /24 blocks, one of which (74.143.180.0/24) displays reverse DNS entries pointing to biz.spectrum.com, indicating a potential lease or historical allocation from a commercial ISP.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
