Summary

University of Missouri-Columbia

United States of America · AI-generated

education research network

The AS handle UNIVERSITY-OF-MISSOURI---COLUMBIA is held by University of Missouri-Columbia.

What it's used for

  • The address space carries university infrastructure and research networks, evidenced by netnames like MONET, MUHSCNET, and MORENET3, and reverse DNS entries pointing to missouri.edu buildings such as Locust-4500X-Locust.bldg.missouri.edu and NEXUS2-Cornell.bldg.missouri.edu.
  • With 138496 IPv4 addresses announced across 14 prefixes and only 2 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants align with the announcer, primarily listing University of Missouri-Columbia, with some blocks registered to University of Missouri - dba the Missouri Research and Education Network (MOREnet).
  • The inventory is finely subdivided into multiple /16, /17, /18, and smaller blocks, reflecting internal site-by-site segmentation typical of a large academic estate.

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 1,772 prefixes, as published 2026-10-15. 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.
