Summary

United States of America · AI-generated

government internal us federal

NARA is the autonomous system for the National Archives and Records Administration.

What it's used for

  • The address space carries internal government network traffic, identified by the consistent NARANET netname across all registered prefixes.
  • The AS announces 8192 IPv4 addresses across 7 prefixes while maintaining only 1 observed neighbour, a ratio indicative of a self-contained internal corporate estate rather than a transit or access provider.

Notable

  • All registrants align with the announcer, with every prefix registered to the National Archives and Records Administration under the NARANET netname.
  • The inventory consists of a single contiguous block within the 207.245.160.0/20 range, subdivided into smaller /21, /23, and /24 prefixes for internal segmentation.

Internet exchanges

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

Transit providers

1 upstream, 0 downstream and 1 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
