Summary
US Department of Defense
government military legacy
AS5376 belongs to the United States Department of Defense, registered under the
DNIC-ASBLK-05120-05376 block held by the DoD Network Information Center.
What it's used for
- Routing for a US military network. Only the block-level DoD registration is public; the registry does not name the specific command or installation this AS number serves.
Notable
- Government address space, used for defense networking rather than for commercial subscribers or hosting.
- ARIN records the enclosing DNIC block as registered in 1995.
Interesting
- AS5376 is the last AS number in its DoD block. The very next number, [AS5377](https://asn.ipinfo.app/AS5377), opens a range administered by the RIPE NCC in Europe, so this ASN sits right on the boundary between the DoD's reserved run and the European registry's space.
