Innsbruck · Austria
PeeringDB records one exchange in Innsbruck, Tirol-IX, which is the city's best connected fabric with 14 participants, alongside four colocation facilities holding 12 network presences between them. Datencenter 3 - Innsbruck accounts for 10 of those networks. An address that geolocates to Innsbruck reflects an operator's registry record rather than a confirmed device location.
Internet exchanges in Innsbruck
An exchange is a shared switch where networks hand traffic to each other directly. Participant counts come from PeeringDB, where each network maintains its own record.

What a Innsbruck IP address tells you
Tirol-IX carries all of the exchange peering PeeringDB records in Innsbruck, and 14 participants sit on that fabric. The rest of the city's recorded capacity is in colocation, where four facilities hold 12 network presences. Datencenter 3 - Innsbruck holds 10 of them, IKB - Rechenzentrum1 and IKB - Rechenzentrum2 list one network each, and IKB - Rechenzentrum Karwendel lists none. None of Austria's mobile operators, A1 Telekom Austria, Drei and Magenta Telekom, appear in the carrier ASNs recorded against Tirol-IX.
An address that a database places in Innsbruck may belong to a device far from the city. Operators announce address blocks from one registry record that covers the whole network, and mobile traffic out of those blocks leaves through a small number of gateways that need not sit in Tirol. Geolocation providers copy the location the operator publishes for a prefix, so a block whose registry entry names Innsbruck reads as Innsbruck for every subscriber on it, wherever the phone is.
Anyone checking an Innsbruck address learns more from the origin ASN and the netname on the specific prefix than from the city label. A1 Telekom Austria announces mobile traffic from AS8447 and AS8562, Drei from AS8437 and AS25255, and Magenta Telekom from AS8412, so a prefix originated by one of those is mobile whatever city a database prints. A prefix originated by one of the 14 networks on Tirol-IX points instead at fixed infrastructure in or near the city.

Questions
Which internet exchanges are in Innsbruck?
PeeringDB records one, Tirol-IX, with 14 participants. Everything else registered in the city is colocation, four facilities carrying 12 network presences between them, and 10 of those presences are in Datencenter 3 - Innsbruck.
Do Austrian mobile carriers peer in Innsbruck?
The registry does not show it. Tirol-IX has no carrier ASNs recorded against it, so A1 Telekom Austria, Drei and Magenta Telekom have no listed presence on the Innsbruck fabric. They may still reach the city over transit or private links PeeringDB does not record.
Does an IP that geolocates to Innsbruck mean the device is there?
No. The city label comes from what the operator published for the address block, and a mobile block can cover a wide area while traffic exits through a few gateways. Read the origin ASN and the netname on the prefix to see which network announces it.
