About this network

An early US Department of Defense allocation from the block DNIC-ASBLK-01550-01601, registered to the DoD Network Information Center (DNIC).

What it's used for

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

• The low AS number reflects an allocation from the internet's earliest years, handed out roughly sequentially.
