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

• US Army networking. The address blocks it originates are registered to Headquarters, USAISC — the Army's information-systems command, whose registry contact sits at Fort Huachuca, Arizona.

Notable

• A government / military network, not a commercial ISP or host.
• The blocks carry theatre-oriented names: several are labelled KOREA1 through KOREA6, alongside one named for the Yuma Proving Ground, plus space from the DoD's 215.0.0.0/8.
• The ASN registration itself is generic to the DoD block. The Army attribution comes from the registration of the address space it announces, not from the AS record.

Interesting

• Military ASNs often reveal geography through the names of their address blocks rather than through geolocation, and this is a clear case: the routing is generic, but the block names read like a posture map.
