AS22252 AS22252 - The City of New York
Unclassified ARIN
Summary
The City of New York
government municipal network
AS22252 is operated by The City of New York.
What it's used for
- The address space carries municipal network infrastructure, as indicated by the consistent
CITYNETnetnames across all major prefixes. - The AS announces 194,304 IPv4 addresses across 42 prefixes while maintaining only 2 observed neighbours, a ratio that implies a self-contained internal corporate estate rather than a transit or access provider.
Notable
- All registrants in the evidence pack are listed as "The City of New York," fully agreeing with the AS holder.
- The inventory consists of three primary blocks: 167.153.0.0/17, 157.188.0.0/16 (subdivided), and 161.185.0.0/16 (subdivided), reflecting a finely segmented internal network.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-25, 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
