What a Calgary IP address tells you
Calgary has a single exchange, and YYCIX carries all 93 of the peers PeeringDB records in the city. Colocation is spread wider, with 14 facilities holding 121 network presences and no one site holding most of them. Arrow Calgary DC2 has 29 networks, Datahive 27, and Equinix CL3 and Arrow Calgary DC1 15 each. Rogers operates two of the listed facilities, at 1313 10th Ave SW with six networks and the Franklin Atrium with two. YYCIX lists AS852 from the carrier registry among its participants, and none of the Canadian mobile ASNs appears there.
An address that geolocates to Calgary may be in use far from it. An operator registers an address block against one office address and geolocation databases follow that published record, so every customer on the block inherits the same city. Mobile addresses drift furthest. Telus routes mobile traffic on AS14663, Bell on AS36522, and Rogers on AS18475, AS20453 and AS36676, and traffic on those networks reaches the internet through a small set of gateways rather than from each subscriber's own city.
The origin ASN on the specific prefix answers what a city field cannot. A prefix announced by one of those mobile ASNs belongs to a phone network whatever the label says, while a prefix from a YYCIX participant or from a network racked in Datahive or eStruxture CAL-1 is fixed capacity with hardware in Calgary. The netname and the registered holder on that prefix are the two fields to read next.

Questions
Which internet exchanges are in Calgary?
One. YYCIX, the YYCIX Calgary Internet Exchange, records 93 participants, which is every peer PeeringDB counts in the city. No second exchange is listed, so networks that do not join it interconnect inside the city's 14 colocation facilities or over transit.
Do Canadian mobile carriers peer in Calgary?
YYCIX records one ASN from the carrier registry, AS852, and it is not among the mobile ASNs held by Bell, Rogers, Telus or Freedom Mobile. Rogers does have two named facilities in Calgary, holding six and two networks, but no mobile ASN appears at the exchange.
Does a Calgary IP address mean the device is in Calgary?
No. Databases copy the location an operator publishes for a whole address block, and mobile traffic exits through a few gateways. Check which ASN originates the prefix and what the netname says before you read the city as a device location.
