Autonomous system
AS5052 DNIC-AS-05052
Unclassified ARIN
Summary
United States Department of Defense
government military legacy
DNIC-AS-05052 is one of many autonomous systems registered to the United States Department of Defense through the Defense Network Information Center (DNIC).
What it's used for
- DoD network infrastructure. The registry resolves this AS no further than "United States Department of Defense" —
DNIC-prefixed ASNs are administered centrally and deliberately do not identify a specific base, command, or program.
Notable
- Government and military address space, not commercial: a few /24s within the DoD's very large legacy IPv4 holdings.
- The DoD registered a long run of low ASNs in the same period, a legacy of its role in funding and building the early internet through ARPA and DARPA.
Interesting
- ARIN registered AS5052 in 1995. Anything more specific about what sits behind it is not public, and this card does not guess.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-23, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 2026-10-24. 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.
