education business health us
The AS handle TAMHSC is operated by Texas A&M University System Health Science Center.
What it's used for
- The address space carries internal university and health science center infrastructure, as indicated by the registrant netnames
HSC-BLK-1andHSC-BLK-2. - The AS announces 12,288 IPv4 addresses across 2 prefixes and maintains a single observed neighbour, a ratio that implies an internal corporate or institutional estate rather than a transit or access provider.
Notable
- Both registrants align with the announcer, identified as Texas A&M University System Health Science Center and Network Services.
- The address inventory consists of two distinct IPv4 blocks: 66.64.64.0/19 and 209.21.112.0/20, with no IPv6 prefixes currently announced.

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 1,778 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.
