Education ARIN
Summary
Eastern New Mexico University
education university legacy
AS11570 is Eastern New Mexico University, the public university at Portales in eastern New Mexico. RIS sees 10 IPv4 prefixes currently announced, roughly 3,300 addresses, no IPv6, and a single observed BGP neighbour. (The two-week prefix list holds 12 entries; the extra couple are space seen and since withdrawn.)
What it's used for
Campus connectivity. The reverse DNS is unambiguous and entirely first-party: sampled addresses resolve to TSEH005.ENMU.EDU, TELNV005.ENMU.EDU, GRANB133.ENMU.EDU and RESLAN005.ENMU.EDU — building-named hosts on the university's own enmu.edu domain, with RESLAN naming a residence-hall LAN. Student housing, academic buildings and administrative systems, all under one small AS with one upstream. Three thousand addresses and a single neighbour is a modest regional university's end-site, not a provider.
Notable
Most of the space registers not to the university but to CHECS — the New Mexico Council for Higher Education Computing/Communication Services, the non-profit consortium of the state's higher-education IT organisations, whose members include essentially every institution in New Mexico. Four /24s and a /22 sit under the CHECSN handle, with 192.94.216.0/24 and 192.207.226.0/24 registered directly to ENMU. A statewide education consortium holding address space on behalf of its member campuses is a legitimate shared-allocation pattern, not a third-party registrant of the sort that flags leased or brokered space.
Interesting
One prefix, 216.161.32.0/23, registers to CenturyLink under a legacy Qwest netblock handle — ordinary provider-assigned space announced by the customer, and a small fossil of the carrier consolidation that reached the university's upstream long before it reached its routing table.

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 1,845 prefixes, as published 2026-10-31. 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.
