Summary

US Department of Defense

United States · AI-generated

government military legacy

A US Department of Defense network from the block DNIC-ASBLK-05800-06055,

registered to the DoD Network Information Center (DNIC).

What it's used for

  • US government / military networking. It announces two /24s out of DNIC-NETBLK-199-032-128, a DNIC-held range. The generic block registration does not name a specific base, unit or mission.

Notable

  • A government / DoD network, not a commercial ISP or host.
  • A small footprint — around 500 IPv4 addresses. Many ASNs in the DoD block are like this: a distinct AS number for a single site or system, announcing only the couple of prefixes it actually needs.
  • Part of a contiguous run of ASNs (5800–6055) held by the DoD Network Information Center.
