About this network

The AS handle DNIC-ASBLK-27032-27159 is held by the United States Department of Defense (DoD).

What it's used for

• The address space carries military and government network infrastructure, evidenced by netnames such as FMLTCU, YUMA-SE, NET-DISA-COLS, JCTEU, MEPCOM-NET1, NOR-NAVSHPYD, and CHS-NIPRNET.
• With 1,486,336 IPv4 addresses announced across 856 prefixes and 78 observed neighbours, the ratio indicates a large-scale internal corporate estate rather than a transit provider, consistent with site-by-site segmentation for a massive organization.

Notable

• Registrants include the DoD Network Information Center, Headquarters USAISC, and the Navy Network Information Center (NNIC), all aligning with the DoD announcer.
• The address inventory is finely subdivided into numerous /16, /17, and /18 blocks, reflecting the distributed nature of DoD facilities and commands.
