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 a small set of prefixes from the DNIC-held 204.222.0.0 and 199.208.0.0 ranges. 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 1,000 IPv4 addresses across three prefixes.
  • Part of a contiguous run of ASNs (5800–6055) held by the DoD Network Information Center, and it draws from the same 204.222.0.0 parent block as [AS5957](https://asn.ipinfo.app/AS5957).
