Unclassified ARIN
Summary
US Department of Defense
government military legacy
AS5852 is a US Department of Defense network from the block DNIC-ASBLK-05800-06055, registered to the DoD Network Information Center (DNIC). It is one of the largest ASNs in that block.
What it's used for
- US government / military network operations. The DNIC registration is generic and does not identify a specific command or installation.
Notable
- Government / military space, not a commercial ISP or hosting provider.
- Substantial: roughly 506,000 addresses across some 850 IPv4 prefixes, plus a few IPv6 prefixes. Announcing hundreds of small prefixes under one AS points to a network aggregating many separate sites rather than a single facility.
- Part of the contiguous 5800–6055 block of DoD-held ASNs.

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 2026-10-21. 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.
