Unclassified ARIN
Summary
US Environmental Protection Agency
government infrastructure research
A quarter of a million addresses in four blocks, most of which announce that nobody is home.
What it's used for
- A federal agency's network. 262,400 addresses across four IPv4 prefixes plus one IPv6 prefix, with one observed BGP neighbour.
Notable
- The four blocks are
204.46.0.0/15,134.67.0.0/16,161.80.0.0/16and192.58.247.0/24. - Their netnames are
EPA-NET2,EPA-NET,EPANESCandEPA-RTP-NCC; all four register toEnvironmental Protection Agency. - Twelve addresses were queried for reverse DNS and eight returned a name.
- All eight returned the same name:
unassigned.epa.gov.
Interesting
- A wildcard record reading
unassignedis a network telling anyone who asks which of its addresses are empty. Most operators publish nothing for unused space, which leaves a scanner to guess. This one answers the question directly, across three separate blocks. - Four prefixes for 262,400 addresses is the opposite of every ISP in this range. The space was allocated in large contiguous pieces and has never been broken up, because an agency network has no acquisitions to absorb and no customers to hand pieces to.
- One neighbour means one way in and out. For a network of this size that is a considered choice: everything transits a single connection, which is far easier to watch than several.
EPA-RTP-NCCis the only netname carrying a site code rather than just the organisation, and it labels the smallest block by a wide margin.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-11, 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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
