Summary
Travelers Property Casualty Corp.
business insurance corporate internal
The AS handle TRAVELERSPCAS is held by Travelers Property Casualty Corp., a major US insurance company.
What it's used for
- The address space is an internal corporate estate, with netnames like
STA-170andTHE-TRAV922-16registered to The St. Paul Travelers Companies, Inc. and The Travelers Indemnity Company. - The AS announces 55040 IPv4 addresses across 56 prefixes while maintaining only 2 observed neighbours, a ratio that indicates a self-contained corporate network rather than a transit or access provider.
Notable
- Registrants align with the announcer, showing The St. Paul Travelers Companies, Inc. for the majority of prefixes and The Travelers Indemnity Company for the 12.163.16.0/21 block.
- The inventory consists of finely subdivided blocks, including multiple /20, /21, /22, and /23 prefixes, reflecting site-by-site segmentation typical of a large enterprise.

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 2026-10-27, 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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
