education university research legacy

UIDAHO is the University of Idaho, the state's land-grant university, headquartered in Moscow, Idaho. The AS carries the campus network: every announced prefix is ARIN-registered to the university itself, so there is no ambiguity about who holds it or what it serves.

What it's used for

  • Campus connectivity for students, staff, research and administration — the standard university mix of wired and wireless client networks, departmental servers and central IT.
  • RIS sees 13 IPv4 prefixes / 32,768 addresses and only 2 observed neighbours. That ratio is the classic institutional shape: a very large block of address space reached through a couple of upstreams (for a US public university, typically a commodity provider plus a regional research-and-education network). A commercial network holding 32k addresses would peer with far more than two ASes.

Notable

  • The address count is accounted for almost entirely by a single aggregate, 129.101.128.0/17 — the upper half of the university's 129.101.0.0/16. Everything else in the list (129.101.136.0/22, 129.101.212.0/24, 129.101.234.0/24, 129.101.252.0/22 and the rest) is a more-specific carved out of that same /17, announced for internal traffic-engineering reasons rather than being additional space.
  • No IPv6 is announced at all, which is increasingly unusual for a research university of this size.
  • The registrant list is uniformly UIDAHO / University of Idaho. Nothing third-party appears anywhere in the inventory.

Interesting

  • The low AS number is genuine here rather than a reissue artefact: ARIN records the ASN as registered in December 1998, to the university's Office of Information Technology in Moscow, and it has been held by the same institution since.

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 1,779 prefixes, as published 2026-10-22. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

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.
