AS11808 — UIDAHO
Network type: education
AS11808 announces 11 IPv4 prefixes covering 32,256 addresses and 3 IPv6 prefixes.
About this network
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.
