Summary
US Department of Defense
government military legacy
AS341 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.
