About this network

A US Department of Defense network from the block DNIC-ASBLK-05800-06055, registered to the DoD Network Information Center (DNIC). Its only current announcement is an IPv6 /48 from DREN address space.

What it's used for

• US government / military networking. The single prefix it announces (2001:480:90::/48) sits inside 2001:480::/32, the block registered as DREN-V6 to the High Performance Computing Modernization Program — so this is a site on the Defense Research and Engineering Network.
• The generic DNIC block registration does not name the specific site or unit.

Notable

• A government / DoD network, not a commercial ISP or host.
• It announces no IPv4 at all — its routing presence is IPv6-only, which fits DREN's reputation as one of the earliest and most committed IPv6 deployments in the US government.
• Sibling DREN-connected ASNs in the same DoD block include AS5887 and AS5957.
