Wyoming · network infrastructure

Cheyenne holds more network presence than any other Wyoming city in the snapshot. Lunavi - Cheyenne records four networks and Mountain West Technologies - Cheyenne another three, while Cogent Cheyenne is listed with none. Casper follows, splitting five presences between Mountain West Technologies - Casper and ACT Casper. The remaining ACT sites in Chugwater, Douglas, Wheatland, Riverton, Gillette, Buffalo and Sheridan hold one or two networks each. No internet exchange appears in Wyoming and the snapshot counts zero peers, so networks that want to exchange traffic do it outside the state.

An IP address that geolocates to Wyoming reflects the address the operator registered for that block, not where the device sits. AT&T, T-Mobile and Verizon each run mobile traffic through a small set of ASNs covering wide areas, so a phone in Casper can present an address that a database places in another state. With 21 network presences across the whole of Wyoming, few operators hold address space registered here, and mobile subscribers sit behind gateways well outside the nine cities the snapshot lists.

The origin ASN on the specific prefix tells you more than a city label does. Verizon's mobile traffic alone spans seven ASNs in this snapshot, AS6167 and AS22394 among them, while T-Mobile uses five and AT&T another five. The netname and the registered address on the prefix show which company holds the range and what address it filed. The operator publishes those fields; the city and state a geolocation service reports are worked out from them.
