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