Summary

Express Scripts

United States · AI-generated

enterprise healthcare legacy

EXPRES is Express Scripts, the pharmacy benefit manager headquartered in St.

Louis, Missouri and now part of Cigna's Evernorth business. AS5696 is its

corporate network.

What it's used for

  • Carrying Express Scripts' own traffic — the systems behind prescription claims processing, mail-order pharmacy, and the member and pharmacy-facing services that go with them.

Notable

  • An enterprise network, not a provider: the ~132,000 addresses here belong to the company's own infrastructure rather than to customers.
  • Its upstreams include a DDoS-mitigation network alongside ordinary transit — a defensive posture you would expect from a company sitting on a very large volume of health and prescription data.
