About this network

An early US Department of Defense network, allocated from the DNIC-ASBLK-00306-00371 block registered to the DoD Network Information Center (DNIC).

What it's used for

• US military / Department of Defense networking.

Notable

• A US government / DoD network, not a commercial ISP or host. Registered to the DoD Network Information Center (DNIC), which holds many federal ASNs.
• The low AS number reflects an allocation from the internet's earliest years, handed out roughly sequentially.
• Announces a large amount of legacy DoD IPv4 address space, reflecting the department's early and expansive allocations.

Interesting

• Part of a contiguous block of AS numbers (306–371) reserved for the DoD, a common pattern for early government allocations.
