Salzburg · Austria
PeeringDB records one exchange in Salzburg, SAIX, the Salzburg Internet eXchange, with 17 participants, and four facilities holding 28 network presences between them, most of those at Techno-Z with 18. SAIX is the city's only exchange and its best connected one. An IP that geolocates to Salzburg names the operator that registered the block, not the device's location.
Internet exchanges in Salzburg
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.
| Exchange | Participants | Registry carriers peering |

SAIX Salzburg Internet eXchange - SAIX | 17 | none in the registry |
Exchange records: PeeringDB.
Colocation facilities
Buildings where networks put equipment. The network count is how many PeeringDB members list a presence there, which shows where capacity in the city sits.
| Facility | Networks present | Address |
|---|---|---|
| Techno-Z | 18 | Schillerstraße 30 |
| conova - Datacenter 4/5 | 5 | Karolingerstraße 36a 5020 Salzburg |
| EXA Edge DC Salzburg | 3 | Schillerstraße 30 5020 Salzburg |
| Emit dc1-2 | 2 | Jakob Harringerstrasse 1 |
What a Salzburg IP address tells you
Salzburg's exchange traffic runs through a single point. SAIX has 17 participants and PeeringDB records no second exchange in the city, so that number is also the whole exchange peer count. Colocation carries a comparable weight. Four facilities hold 28 network presences between them, Techno-Z with 18, conova - Datacenter 4/5 with 5, EXA Edge DC Salzburg with 3 and Emit dc1-2 with 2. None of the three Austrian mobile operators appear in the SAIX participant ASNs the registry publishes.
An address that geolocates to Salzburg is often not a device in Salzburg. Operators announce blocks from a registry record that carries one address, and geolocation databases repeat that address for every prefix underneath. Austrian mobile networks add a second step, since subscriber sessions leave through a handful of gateways that need not sit anywhere near the handset. A Salzburg label can therefore ride on traffic from a phone in another part of the country.
Someone checking an address should read the origin ASN and the netname on that exact prefix. No Austrian mobile ASN peers at SAIX in the registry, so a Salzburg-labelled address originated by AS8447, AS8562, AS8437, AS25255 or AS8412 says nothing about a presence at the exchange, only about which operator registered the range. An address tied to one of the four local facilities shows a hosting or regional network as its origin instead.
Mobile carriers in Austria

Questions
Which internet exchange is in Salzburg?
SAIX, the Salzburg Internet eXchange, is the only one PeeringDB records, with 17 participants. Alongside it the registry lists four facilities holding 28 network presences between them, the highest single count being Techno-Z with 18 networks.
Do Austrian mobile carriers peer in Salzburg?
The registry does not record it. SAIX publishes no participant ASN belonging to A1 Telekom Austria, Magenta Telekom or Drei, so PeeringDB gives no evidence of mobile peering in the city. That is an absence in the data rather than proof no connection exists.
Does an IP that geolocates to Salzburg mean the device is there?
No. The city label comes from the location an operator published for the address block, and mobile traffic exits through gateways placed wherever the network wants them. Read the origin ASN and the prefix netname to see which network the address belongs to.
