Summary
Bristol-Myers Squibb
enterprise legacy
BMS-AS is the corporate network of Bristol-Myers Squibb, the American pharmaceutical company headquartered in Princeton, New Jersey.
What it's used for
- Bristol-Myers Squibb's own enterprise network: corporate sites, research and manufacturing facilities, and internet-facing company services.
- It is not a service provider — the address space serves the company itself.
Notable
- The announced footprint is a scatter of small IPv4 blocks (largely
/24s out of165.89.0.0,198.155.0.0and158.117.0.0space) plus a set of IPv6/48s, which is the shape of a multi-site enterprise rather than an ISP. - A large pharmaceutical firm running its own AS is an artifact of the era when big corporations obtained address space and AS numbers directly, before outsourcing connectivity to carriers and clouds became the norm.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
7 upstream, 0 downstream and 14 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,773 prefixes, as published 2026-10-13. 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.
