education university research land-grant

NMSU is operated by New Mexico State University.

What it's used for

  • The address space carries university infrastructure, evidenced by netnames NMSU-Z and NMSU-EXTERNAL registered to "New Mexico State University; NMSU Network Operations".
  • The AS announces 66,816 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating an internal campus network rather than a transit provider.
  • Traffic consists of academic, research, and administrative endpoints for the university's faculty, staff, and students.

Notable

  • Registrants for the primary prefixes align with the announcer, specifically "New Mexico State University; NMSU Network Operations" for 128.123.0.0/16 and 192.65.77.0/24.
  • The inventory includes a large /16 block alongside smaller /23 and /24 blocks, reflecting a consolidated internal 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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
