government military legacy

An early US Department of Defense allocation from the block DNIC-ASBLK-00616-00665,

registered to the DoD Network Information Center (DNIC).

What it's used for

  • US government / military networking. The generic DNIC block registration doesn't name a specific base or unit.

Notable

  • A government / DoD network, not a commercial ISP or host. Part of a contiguous block of DNIC-held ASNs.
  • The low AS number reflects an allocation from the internet's earliest years, handed out roughly sequentially.
