About this network
GWTC is the autonomous system of Golden West Telecommunications Cooperative, Inc., a member-owned telephone and broadband cooperative headquartered in Wall, South Dakota.
What it's used for
Golden West provides internet, telephone and television service across a large rural footprint stretching from South Dakota's western border toward the eastern side of the state. AS6580 originates around 45,000 IPv4 addresses spread over roughly 50 prefixes, mostly /22s in 69.77.0.0/16, 68.69.0.0/16, 216.196.0.0/16 and 64.251.0.0/16. Reverse DNS follows a uniform subscriber pattern under gwtc.net, for example 69-77-192-1.ip4.gwtc.net.
Notable
This is a residential eyeball network. The heavily fragmented prefix list, many small /22s rather than a few large aggregates, is typical of a rural cooperative that grew by adding exchanges and acquiring neighbouring territories over decades.
Golden West traces its telephone service back to 1916 and incorporated as a cooperative in 1952, long before it became an internet provider. ARIN registered AS6580 in May 1996.
