What a Bucharest IP address tells you
InterLAN-IX carries 124 participants, more than the other four Bucharest exchanges combined, with RoNIX at 38, Balcan-IX at 29, DSIX at 11 and RO-IX at 2. Capacity also sits in colocation, where 20 facilities record 277 network presences. NXDATA-1 alone accounts for 115 of those, NXDATA-2 for 81 and Voxility IR1 for 23. Among Romania's mobile operators, Orange Romania's AS8953 appears at InterLAN-IX and RoNIX, and Vodafone Romania's AS12302 at RoNIX. AS35725, which the registry lists for both Vodafone Romania and Telekom Romania, is in none of the city's exchange records.
An address that geolocates to Bucharest tells you where an operator says the block lives, not where the handset or server sits. Romanian networks announce prefixes from a single registry record that often names the company address, and geolocation databases read that published location and copy it. Mobile traffic adds a second step, because it leaves through a small number of gateways that need not be near the subscriber. A customer in another county can carry a Bucharest address the whole time.
Someone checking a Bucharest address should read the origin ASN and the netname on the exact prefix rather than trust the city label. The registry gives AS8953 for Orange Romania, AS12302 for Vodafone Romania and AS35725 for Vodafone Romania and Telekom Romania together, so a prefix originating outside those numbers is not a Romanian mobile connection whatever a database prints. An ASN registered to a hosting or colocation company points at a machine in a facility such as NXDATA-1, and reverse DNS on the address usually confirms which of the two it is.
Mobile carriers in Romania

Questions
Which internet exchanges are in Bucharest?
PeeringDB lists five exchanges in Bucharest. InterLAN-IX has 124 participants, RoNIX 38, Balcan-IX 29, DSIX 11 and RO-IX 2. InterLAN-IX is the best connected by participant count, and the city's 20 colocation facilities record 277 network presences on top of the exchange totals.
Do Romanian mobile carriers peer in Bucharest?
Orange Romania's mobile ASN 8953 is recorded at InterLAN-IX and RoNIX, and Vodafone Romania's 12302 at RoNIX. AS35725, listed for both Vodafone Romania and Telekom Romania, appears at no Bucharest exchange in the registry. A missing entry means nothing was published, not that local connectivity is absent.
Does an IP that geolocates to Bucharest mean the device is there?
No. Geolocation databases follow the location an operator publishes for the address block, and Romanian mobile networks route wide regions through a small number of gateways. A Bucharest result is a reasonable guess about the operator's registration, not evidence about where the phone or server is.
