Summary
University of Texas System (UT Permian Basin)
education university legacy
UTPB-AS-10812 is registered to the University of Texas System, and the handle points to its Permian Basin campus in Odessa, Texas. RIS sees 2 IPv4 prefixes carrying 12,288 addresses, no IPv6, and 1 observed neighbour.
What it's used for
A university campus network. The announcement set is just 204.158.160.0/19 and 204.158.144.0/20 — contiguous legacy ARIN space, announced whole with no deaggregation at all. That carries the usual campus estate: administrative systems, the library and academic computing, faculty and departmental servers, lab and research networks, campus wireless and student housing.
Notable
12,288 addresses for a single regional campus is generous by modern standards and only makes sense historically. Universities were among the earliest institutional adopters of the internet and were allocated address space on a scale that matched enrolment rather than need, long before NAT and RFC 1918 space were the default. The clean, unfragmented pair of announcements says the space has never been broken up or partly sold off.
Interesting
One observed neighbour is unusual for an institution this size, and it is the normal shape for a US public university: campuses typically do not buy commodity transit directly, they reach the internet through their state's research and education network, so the whole campus appears behind a single adjacent AS. It also means the ASN exists mostly to hold and originate the space, not to multihome it. There is no IPv6 in the announcement set.

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 2026-10-24. 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.
