About this network

A US Department of Defense network from the block DNIC-ASBLK-05120-05376, registered to the DoD Network Information Center (DNIC).

What it's used for

• Operational US Navy networking. Nearly all of the space it originates comes from legacy 205.x blocks registered to the Navy Network Information Center (NNIC).

Notable

• A government / military network, not a commercial ISP or host.
• The ASN registration is generic to the DoD block, so no specific base or unit is publicly identified. The Navy attribution comes from the registration of the address blocks it announces.
• A small footprint — a handful of /24s — compared to the larger Navy ASNs in the same block.
