Summary

United States Nuclear Regulatory Commission

United States of America · AI-generated

government nuclear regulatory internal

The AS handle NRC-NET is held by the United States Nuclear Regulatory Commission.

What it's used for

  • The address space is entirely registered under the netname USNRC for the United States Nuclear Regulatory Commission, indicating a dedicated government network for regulatory operations.
  • The AS announces 65,536 IPv4 addresses across 43 prefixes and 7 IPv6 prefixes, while maintaining only 3 observed neighbours. This high address-to-neighbour ratio characterizes the network as an internal corporate estate with site-by-site segmentation rather than a transit or access provider.

Notable

  • All sampled registrants align perfectly with the announcer, consistently identifying the United States Nuclear Regulatory Commission.
  • The inventory consists of a single contiguous IPv4 block (148.184.0.0/19 and subnets) and a series of IPv6 prefixes under 2620:129:2000::/46, reflecting a finely subdivided internal infrastructure.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,773 prefixes, as published 2026-10-13. 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.
