Summary

United States Food and Drug Administration

United States of America · AI-generated

government agency internal network

The AS handle ASN-FDA is held by the United States Food and Drug Administration.

What it's used for

  • The address space carries internal agency infrastructure, evidenced by the consistent netname FDA-NET and registrant contacts including FDA NOC, FDA Abuse, and FDA Tech.
  • The AS announces 64512 IPv4 addresses across 6 prefixes and 4 IPv6 prefixes, with only 1 observed neighbour, indicating a standalone internal network rather than a transit or access provider.

Notable

  • All registrants for the announced prefixes align with the announcer, listing the United States Food and Drug Administration as the primary entity.
  • The address inventory is finely subdivided within the 150.148.0.0/17 block, reflecting site-by-site or departmental segmentation typical of a large corporate or government estate.

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 2026-10-23. 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.
