What a South Dakota IP address tells you
Sioux Falls holds twelve of South Dakota's seventeen network presences, spread over five buildings. SDN Communication Mark Shlanta Technology Park has four networks and the SDN Communications campus three, with TierPoint Sioux Falls - East and Midco Sioux Falls at two each and TierPoint Sioux Falls - West at one. Golden West Rapid City Skyline Facility holds three networks, and Midco Yankton two. No internet exchange appears in South Dakota and the snapshot counts zero peers, so networks in these buildings exchange traffic outside the state.
An IP address that geolocates to South Dakota reports the address its operator registered for the block. Mobile networks concentrate subscribers behind gateways covering several states, so a device on AT&T, T-Mobile or Verizon in Rapid City can present an address a database places elsewhere. Only three cities appear in the state's records, and the seventeen network presences in them belong to networks whose registrations may name an address far from the equipment carrying the traffic.
The origin ASN on the prefix, together with the netname, tells you which company announces the range. Verizon's mobile traffic uses seven ASNs in this snapshot and AT&T's five, and any one of them can cover subscribers across a wide area. A city returned by a geolocation lookup is read out of the operator's own filing, so check the filing rather than the label it produces.

Questions
How many data centres are in South Dakota?
The snapshot lists 7 facilities in South Dakota, five of them in Sioux Falls and one each in Rapid City and Yankton. They hold 17 network presences, and SDN Communication Mark Shlanta Technology Park carries the most at four.
Is there an internet exchange in South Dakota?
No. The snapshot records no exchange and zero peers in South Dakota. Networks in Sioux Falls, Rapid City and Yankton hand traffic to transit or carry it to exchanges in other states, so traffic between two South Dakota providers can leave the state and come back.
Can I get an IP address in South Dakota?
Placement follows the operator's address registration rather than a customer's request. An address reads as South Dakota when the network holding the block registered a South Dakota address for it. Mobile ranges are often registered once for a wide region, so state placement is not something a subscriber picks.
