government military legacy

A US Department of Defense network (DISACENT-NIPR-ASN), associated with the

Defense Information Systems Agency (DISA) and the Non-classified Internet

Protocol Router Network (NIPRNet). Registered to the DoD Network Information

Center (DNIC).

What it's used for

  • Carrying unclassified DoD traffic and providing gateway connectivity between military networks and the public internet.

Notable

  • A US government / DoD network, not a commercial ISP. NIPRNet is managed by DISA as part of the Defense Information Systems Network (DISN).

Interesting

  • The low AS number reflects an early allocation, dating to the era when the DoD's networks were foundational to the internet's growth.
