Summary
United States Postal Service
government enterprise legacy
USPS-001 is the United States Postal Service, the federal agency that delivers
the mail. This is the Postal Service's own network, not a commercial ISP.
What it's used for
- Corporate and operational networking for USPS: retail post offices, mail processing and distribution centers, and the agency's public-facing systems such as usps.com tracking and shipping tools.
Notable
- An IP here belongs to a US federal government agency, so traffic from this AS is Postal Service infrastructure or staff, not consumer broadband.
- The entire announced footprint sits inside the legacy
56.0.0.0/8range, including large aggregates like56.105.0.0/16and56.235.0.0/16. Roughly 196,000 addresses are routed here, a substantial block for a single agency.
Interesting
- USPS is one of the few civilian federal agencies that operates its own autonomous system rather than sitting behind a carrier or a shared government network.
