About this network

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.net and netnames such as CPWS-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.
