Summary
Columbia Power and Water Systems
utility municipal business other
COLUMBIAPWS is the autonomous system for Columbia Power and Water Systems.
What it's used for
- The address space carries internal utility infrastructure, evidenced by reverse DNS entries like
host-66-211-18-254.cpws.netand netnames such asCPWS-66-211-16-0-20. - The AS announces 11,776 IPv4 addresses across 18 prefixes with only 4 observed neighbours, a ratio indicating a small, self-contained corporate or municipal network rather than a transit or large-scale access provider.
Notable
- All registrants in the RDAP data are listed as Columbia Power and Water Systems, fully agreeing with the AS holder.
- The address inventory consists of three distinct blocks (66.211.16.0/20, 76.9.160.0/20, and 138.43.210.0/23) that are finely subdivided into smaller prefixes, consistent with site-by-site segmentation for a local utility.

Interconnection

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 2026-10-21, 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 1,779 prefixes, as published 2026-10-22. 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.
