Summary
Texas Tech University Health Sciences Center El Paso
education healthcare university research
TTUHSC-ELP is operated by Texas Tech University Health Sciences Center El Paso.
What it's used for
- The address space carries institutional traffic for a public health sciences university, with netnames
TTUHSC-EL-PASOandTTUHSCEPregistered to the same entity. - The AS announces 12,288 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 4 observed neighbours, a ratio consistent with an on-campus access network rather than a transit provider.
- Traffic from this AS consists of staff, students, and clinical systems associated with the university's medical and health science programs in El Paso, Texas.
Notable
- Both registrants in the RDAP data match the AS holder, confirming the space is directly owned and not leased.
- The address inventory is compact, comprising a /19 and a /20 in IPv4 and a single /44 in IPv6, typical for a single-site academic institution.

Internet exchanges
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 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,783 prefixes, as published 2026-10-20. 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.
