Summary
U.S. Department of Justice
government infrastructure
A federal department with thirty-four announcements and one observed upstream.
What it's used for
- A national justice department's network. Thirty-four IPv4 prefixes and seventeen IPv6 prefixes announced from the United States, with a single observed BGP neighbour.
Notable
- Every IPv4 prefix falls inside
149.101, split down to individual/24blocks, so one allocation is announced as thirty-four separate routes. - Every resolved block carries the same netname,
USDOJ, and the same registrant, so the registry distinguishes none of them. - The registrant spells the country abbreviation with spaces inside it, which is enough to defeat an exact-match search for the more common form.
- The IPv6 announcements form a ladder from a
/37down through successive lengths to two adjacent/48blocks, with two further/48prefixes from an unrelated part of the allocation. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- One observed neighbour for a department this size is the finding, and it is a statement about what the collectors see rather than about the network. Government traffic that transits a shared federal network reaches the public internet through it, so the department's own peering is invisible from outside.
- Splitting one range into thirty-four routes while publishing nothing in reverse DNS is a network organised entirely for its own purposes. The deaggregation shows internal structure exists; nothing in the record says what any piece of it is.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, 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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
