hospital business education us
USC-UNIVERSITY-HOSPITAL is operated by Keck Hospital of USC, formerly known as USC University Hospital.
What it's used for
- The address space carries internal hospital infrastructure, evidenced by netnames such as
USC-HOSPITAL-207-151-0-0-20andUSCUH-NH(Network Operations Center). - The AS announces 21 IPv4 prefixes totaling 21,760 addresses with only 2 observed neighbours, indicating a self-contained internal corporate estate rather than a transit or access network.
Notable
- All registrants in the evidence pack consistently identify as
USC-University Hospital, matching the AS handle and confirming a single organizational owner. - The operator was formerly known as USC University Hospital before being renamed Keck Hospital of USC, a private teaching hospital affiliated with the University of Southern California.
- The inventory consists of 21 IPv4 prefixes with no IPv6 announcements, showing a finely subdivided internal address space typical of a large institutional campus.

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 2026-10-17, 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 2026-10-17. 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.
