Rosario · Argentina
PeeringDB records no internet exchange in Rosario, Argentina. The city appears as three colocation facilities holding 15 network presences, with Cabase ROS accounting for 11 and Nubenet and Cirion Rosario - ROS1 for 2 each. An address that geolocates to Rosario reports an operator's registry entry, not where a device sits.
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 |
|---|---|---|
| Cabase ROS | 11 | Palacio Minetti Piso 11 |
| Nubenet | 2 | Paraguay 1416 |
| Cirion Rosario - ROS1 | 2 | Av. Circunvalacion 25 de Mayo 1545 bis (entre Martinez Estrada y Sorrento |
What a Rosario IP address tells you
Rosario's role in the registry is small and entirely colocation-based. No exchange is recorded, so the city has no participant entries at all, and its 15 network presences sit in three facilities. Cabase ROS holds 11 of them, with Nubenet and Cirion Rosario - ROS1 at 2 apiece. Argentina's mobile operators, Claro (AS11664), Movistar (AS11315, AS22185, AS262175) and Personal (AS7303), have nothing to peer with here in the exchange sense, whatever private links they run inside these buildings.
An address labelled Rosario therefore rests on thin evidence. Operators publish one location per address block in their registry record, and geolocation databases inherit it wholesale, so thousands of addresses can carry a Rosario tag from a single administrative line. Mobile addressing pulls in the same direction, since subscriber traffic reaches the internet through a limited set of national gateways rather than through the town the handset is standing in.
Look at the origin ASN and the netname on the specific prefix before trusting a city field. If the prefix originates from one of the Argentine mobile ASNs, the Rosario label describes registration and nothing about a tower. If the netname belongs to a network present in Cabase ROS or Cirion Rosario - ROS1, the address is more plausibly attached to hardware in one of those facilities.

Questions
Which internet exchanges are in Rosario?
PeeringDB lists none. Rosario's entries are colocation facilities: Cabase ROS with 11 networks, Nubenet with 2, and Cirion Rosario - ROS1 with 2. That gives 15 network presences in the city and no exchange participant count at all.
Do Argentine mobile carriers peer in Rosario?
The registry records no Rosario exchange, so no carrier peering is published for the city. Claro (AS11664), Movistar (AS11315, AS22185, AS262175) and Personal (AS7303) may hold private interconnection in local facilities, but PeeringDB does not show it either way.
Does an IP that geolocates to Rosario mean the device is there?
No. Databases repeat the location an operator registered for the whole address block, and Argentine mobile sessions leave through a few gateways. Check which ASN originates the prefix and what the netname says before reading anything into the city name.
