Summary

US Department of Defense

United States · AI-generated

government military legacy

A US Department of Defense network (DNIC-AS-01649), registered through the Defense Network Information Center (DNIC), which holds many federal and military ASNs.

What it's used for

  • US government / DoD operational networking.

Notable

  • A government / military network, not a commercial ISP or host. The generic DNIC registration does not identify a specific base or unit.
  • The low AS number reflects an early Department of Defense allocation from the internet's first years.
