Summary
City of Gaithersburg
government municipal network
The AS handle GAITHERSBURGMDGOV is held by the City of Gaithersburg.
What it's used for
- The address space carries municipal infrastructure, evidenced by reverse DNS entries such as
cog64.ci.gaithersburg.md.usandcog127.ci.gaithersburg.md.us. - The network announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or access provider.
- Traffic from this AS consists of internal city government operations, including administrative systems and municipal services hosted on the city's own infrastructure.
Notable
- The RDAP registrant for the announced prefix 209.122.172.0/24 is listed as RCN with netname RCN-BLK-3, while the AS holder is the City of Gaithersburg, indicating the address space was originally allocated to RCN before being assigned to the municipality.
- The inventory consists of a single /24 block, representing a compact and dedicated address estate for the city's network.

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 2026-10-27, 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: 447 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.
