Summary

US Department of Defense

United States · AI-generated

government military legacy

A US Department of Defense network from the block DNIC-ASBLK-05120-05376,

registered to the DoD Network Information Center (DNIC).

What it's used for

  • US government / military networking. It originates just two /24s, both from 214.0.0.0/8, one of the DoD's reserved /8s.

Notable

  • A government / military network, not a commercial ISP or host.
  • The generic DNIC block registration doesn't name a specific base or unit.
  • A minimal footprint, typical of a DoD ASN standing up a single site or system rather than a broad enterprise network.

Interesting

  • The Department of Defense holds AS5120 through AS5376 as one contiguous DNIC block, so this ASN's neighbours are sibling military networks rather than unrelated organisations.
