Summary
US Department of Defense
government military legacy
A US Department of Defense network (DNIC-AS-00289), one of many federal ASNs registered to the DoD Network Information Center (DNIC).
What it's used for
- US military and defense networking. The DNIC registration does not identify a specific base or unit.
Notable
- A US government / DoD network, not a commercial ISP or host. The low AS number reflects an early-internet allocation.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
