Summary

United States Department of Defense

United States of America · AI-generated

government defense military network

The AS handle DNIC-ASBLK-27032-27159 is held by the United States Department of Defense (DoD).

What it's used for

  • The space carries DoD network infrastructure, evidenced by the netname DNIC-NET-214 and registrant DoD Network Information Center.
  • The AS announces a single IPv4 prefix, 214.24.22.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, the low address-to-neighbour ratio suggests a highly segmented internal corporate estate rather than a transit or access network.

Notable

  • The registrant DoD Network Information Center aligns directly with the announcer, the United States Department of Defense.
  • The address inventory consists of a single /24 block, indicating a tightly controlled and specific allocation within the broader DoD network estate.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
