Summary
University of Texas Health Science Center at Houston
education university research legacy
The campus network of The University of Texas Health Science Center at Houston (UTHealth Houston), the UT System's academic health science centre, under the handle UTHSC-H.
What it's used for
- Connectivity for the university's medical, dental, nursing, public health and biomedical informatics schools, plus their research computing and clinical affiliates.
- Announces two legacy /16s,
129.106.0.0/16and139.52.0.0/16, a class-B pair typical of a university that got onto the Internet early and never gave the space back.
Notable
- Institutional address space: it serves faculty, students, labs and hospital- adjacent systems rather than paying subscribers.
- The campus sits in the Texas Medical Center, so the network neighbours a dense cluster of other academic and hospital ASNs in Houston.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 2026-10-23. 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.
