Unclassified ARIN
Summary
American Express Company
enterprise finance legacy
The corporate network of American Express Company, the US payments and financial services firm, registered under the handle AMERICAN-EXPRESS from Phoenix, Arizona.
What it's used for
- Enterprise connectivity for a global card issuer and payments network: corporate offices, data centres, and the systems behind card authorisation, merchant services and customer-facing sites.
- Roughly thirty-five thousand IPv4 addresses, sized for a large multinational's own estate rather than for resale.
Notable
- A financial-institution network. The address space serves one company's staff, applications and payment infrastructure; none of it is sold to subscribers.
- ARIN records the assignment in early 1996, placing American Express among the earlier large US enterprises to operate an autonomous system of its own.

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.
