Autonomous system

Unclassified ARIN
Summary
United States Department of Defense
government military legacy
DNIC-AS-05052 is one of many autonomous systems registered to the **United
States Department of Defense** through the Defense Network Information Center
(DNIC).
What it's used for
- DoD network infrastructure. The registry resolves this AS no further than "United States Department of Defense" —
DNIC-prefixed ASNs are administered centrally and deliberately do not identify a specific base, command, or program.
Notable
- Government and military address space, not commercial: a few /24s within the DoD's very large legacy IPv4 holdings.
- The DoD registered a long run of low ASNs in the same period, a legacy of its role in funding and building the early internet through ARPA and DARPA.
Interesting
- ARIN registered AS5052 in 1995. Anything more specific about what sits behind it is not public, and this card does not guess.
