About this network

COSL-01 is the autonomous system for the City of Sugar Land.

What it's used for

• The address space carries residential dynamic IP addresses, evidenced by reverse DNS records pointing to dynamic.ip.windstream.net (e.g., h64.81.16.72.dynamic.ip.windstream.net).
• The AS announces 512 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a small municipal access network rather than a transit provider.

Notable

• Registrants for both announced prefixes (72.16.81.0/24 and 168.151.254.0/24) are listed as CITY OF SUGAR LAND or City of Sugar Land, matching the AS holder.
• The inventory consists of two /24 blocks, one of which (72.16.81.0/24) shows Windstream reverse DNS, suggesting the city operates or leases this space for local broadband services.
