Summary

American Express Company

United States · AI-generated

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.
