About this network

AS337 is a US Department of Defense network, part of the block registered to the DoD Network Information Center (DNIC-ASBLK-00306-00371).

What it's used for

• Operational networking for US Department of Defense sites. The specific unit isn't publicly identified beyond the DoD registration.

Notable

• An IP here belongs to a US government / military network, not a commercial ISP or hosting provider.
• Registered to the DoD Network Information Center (DNIC), which holds a large contiguous block of low-numbered federal ASNs.

Interesting

• The low AS number reflects an early-internet allocation. The parent DNIC block (ASNs 306–371) dates to 1989, when the DoD received many sequential numbers at once.
