Summary
US Department of Defense
government military legacy
AS6043 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.
- It is one of the quietest ASNs in the block: no IPv4 announcements at all, just a single IPv6
/48out of2001:480::/32. An AS in this state is typically held for a network that is dormant, internal, or routed under another number. - 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.
