Cluj Napoca · Romania
PeeringDB records no internet exchange in Cluj Napoca and counts zero peering participants. Seven colocation facilities are listed, holding nine network presences between them, with efectRO DC1 the busiest at three. A Cluj Napoca IP address therefore reflects an operator's registry entry rather than any local interconnection point the database can show.

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.

What a Cluj Napoca IP address tells you
PeeringDB shows no exchange in Cluj Napoca, so the city's whole entry is colocation. Seven facilities carry nine network presences between them. efectRO DC1 holds three and Compania de Informatica Aplicata two, while GTS Telecom DC Cluj-Napoca, Starnet Media Cluj-Napoca, efectRO DC2 and DataWave#1 record one each, and Hosting Data Center Cluj records none. With no exchange record, the registry cannot show any of Romania's mobile operators peering locally, and the mobile ASNs 8953, 12302 and 35725 appear nowhere in the city's data.
An address that geolocates to Cluj Napoca can still be answered by hardware somewhere else. Romanian operators announce address blocks under one registry record covering the whole network, and geolocation providers copy the location that record publishes. Mobile traffic adds another step, since it leaves through a small number of gateways that need not be near the subscriber. A block sold to customers around Cluj Napoca can be routed and terminated well outside the city, and the database has no way to see that.
Reading the origin ASN on the exact prefix says more than the city name. The registry gives AS8953 for Orange Romania, AS12302 for Vodafone Romania and AS35725 for Vodafone Romania and Telekom Romania together, so a prefix that originates outside those numbers is not a Romanian mobile connection whatever label a database prints. The netname on the block usually identifies its holder, and reverse DNS often shows whether an address belongs to a mobile pool or to equipment in one of the city's seven facilities.

Questions
Which internet exchanges are in Cluj Napoca?
PeeringDB records none. Its Cluj Napoca entry is seven colocation facilities holding nine network presences between them, the most in efectRO DC1 with three, and a peering participant count of zero. Any interconnection the city's networks do with each other is not published in this registry.
Do Romanian mobile carriers peer in Cluj Napoca?
The registry shows no exchange in the city, so it records no peering there by Orange Romania, Vodafone Romania or Telekom Romania. Their mobile ASNs 8953, 12302 and 35725 appear in Romania's data elsewhere. Silence here means no published record, not proof that local equipment is absent.
Does an IP that geolocates to Cluj Napoca mean the device is there?
Not reliably. The city result comes from the location an operator publishes for the address block, and one record can cover a network reaching far past Cluj Napoca. Mobile addresses in particular follow the gateway, so treat the city as the operator's claim rather than a position.
