AS14762 AMGEN
Unclassified ARIN
Summary
AMGEN, Inc.
enterprise research business
Eleven blocks, one netname, and the only two hostnames that answer are a mail discovery endpoint and a development server.
What it's used for
- A biotechnology company's corporate network. 4,864 addresses across 11 IPv4 prefixes, with six observed BGP neighbours and no IPv6 announced.
Notable
- All 11 blocks carry the netname
AMGEN, registered toAMGEN, Inc., with no numbering or variation between them. - Two of eighteen sampled addresses returned names:
msautodiscover.amgen.comandcrisfoundationdev.amgen.com.
Interesting
- A single unvaried netname across eleven separately announced blocks is unusual discipline. Most estates this size accumulate suffixes, dates and half-remembered project names; this one was filed by somebody who decided the company name was sufficient and then held the line.
- The two hostnames that do answer are the two most interesting kinds. One is the endpoint mail clients query to configure themselves, which confirms the mail platform in use to anyone who looks. The other ends in the letters that mark a development system, published from the same address space as production.
- Six neighbours for a company that does not sell connectivity means several carriers, which is what research and manufacturing sites in different regions each buying local transit looks like from outside.
- Address blocks scattered across three unrelated ranges, all under one name, trace a company that kept buying small allocations rather than renumbering into one.

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 2026-10-14, 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 1,771 prefixes, as published 2026-10-15. 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.
