Summary
U.S. Department of State
government legacy
USDOS is the network of the U.S. Department of State, the federal executive department responsible for American foreign policy and diplomacy. The registrant address on file is the Harry S Truman Building, 2201 C Street NW, Washington DC.
What it's used for
- Announcing the Department's own address estate. The routed space is drawn almost entirely from
169.252.0.0/15(DOS-US), a direct ARIN allocation made to the Department in 1996, the same month the AS number itself was registered. - Reverse DNS on the announced prefixes resolves under
state.gov, confirming the space is used by the Department itself rather than delegated to a contractor network.
Notable
- A civilian-agency government AS: the address space serves departmental infrastructure and the worldwide diplomatic mission network, not the public.
- The AS number and the
/15were registered together in July 1996, which is unusual and a good sign that both records are genuine rather than later re-registrations. - Distinct from US military networks, which sit under the Defense Department's
DNICAS blocks rather than here.
