About this network

AS6040 is a US Department of Defense network, registered as part of the block DNIC-ASBLK-05800-06055 held by the DoD Network Information Center (DNIC).

What it's used for

• US government / military networking. The block registration is generic and does not name a specific base, command or unit.

Notable

• An IP here belongs to a government / military network, not a commercial ISP or hosting provider.
• Its ~19,000 IPv4 addresses arrive as fifty-odd mostly-/24 routes pulled from several different legacy DoD ranges (140.185.x, 130.16.x, 155.19.x, 199.114.x) rather than from one contiguous block.
• Part of a large contiguous run of DoD-held ASNs (5800–6055), delegated to the DNIC as a block rather than one at a time.
