Summary

United States Department of Defense

United States · AI-generated

government military legacy

One of the many AS numbers registered to the United States Department of Defense, under the generic handle DNIC-AS-03529.

What it's used for

  • Department of Defense networking. The public registry records identify only the DoD as the holder; the specific command, base, or program behind this particular AS is not published.

Notable

  • DNIC stands for the Defense Network Information Center, the registry that historically administered the DoD's internet number resources. Hundreds of low-numbered ASNs and a large share of the legacy IPv4 space carry DNIC-AS- or DNIC-ASBLK- handles.
  • Government address space (about 1,280 IPv4 addresses here), with no consumer or hosting use.

Interesting

  • The DoD's early and heavy involvement in the internet's creation left it with an unusually large footprint at the bottom of the AS-number range.

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 1,779 prefixes, as published 2026-10-22. 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.
