United States · AI-generated

government military legacy

A US Department of Defense network registered as DNIC-AS-03954 through the DoD

Network Information Center (DNIC).

What it's used for

  • US government and military network operations. The registration identifies only the Department of Defense; the specific site, command, or unit behind it is not publicly stated.

Notable

  • A government network, not a commercial ISP or hosting provider. The DoD holds a large number of ASNs registered under DNIC-* handles, many of them in the low-numbered range from the internet's early years — a legacy of the military's role in funding and building the ARPANET.
