Summary
US Department of Defense
government military legacy
An early US Department of Defense allocation (DNIC-AS-00257), registered through
the DoD Network Information Center (DNIC), which holds many federal ASNs.
What it's used for
- US government / military networking. The generic DNIC registration does not identify a specific base or unit.
Notable
- A US government / DoD network, not a commercial ISP or host.
- The low AS number reflects a very early allocation, handed out roughly sequentially in the internet's first years.
