AS5641 TVH-289 - UNIVERSAL HEALTH SERVICES
Unclassified ARIN
Summary
Universal Health Services
enterprise legacy
A corporate network of Universal Health Services, Inc. (UHS), the King of Prussia, Pennsylvania hospital and behavioural-health operator, registered under the handle TVH-289.
What it's used for
- Enterprise connectivity for the healthcare group: a single 256-address block routed by UHS for its own facilities and systems, not sold to customers.
Notable
- Healthcare enterprise address space, so it sits behind clinical and corporate systems rather than public hosting.
- ARIN registered AS5641 to UHS in December 2024. The low number is a very recent reassignment and carries no early-internet history.
Interesting
- The AS name
TVH-289does not spell out the company at all. It is an opaque handle, and only the ARIN registrant record identifies the network as Universal Health Services.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
