AS7246 — BMS-AS
AS7246 announces 23 IPv4 prefixes covering 8,448 addresses and 7 IPv6 prefixes.
About this network
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 of 165.89.0.0, 198.155.0.0 and 158.117.0.0 space) 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.
