Budapest · Hungary
PeeringDB records one exchange in Budapest, BIX (Budapest Internet eXchange), with 103 participants, plus six colocation facilities holding 145 network presences between them, the fullest being Dataplex Budapest with 65. An address that geolocates to Budapest shows where an operator registered the block, not where the device using it sits.
Internet exchanges in Budapest
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 |
|---|---|---|
BIX Budapest Internet eXchange | 103 |
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 |
|---|---|---|
| Dataplex Budapest | 65 | Asztalos Sandor utca 13. |
| BIX Building (Victor Hugo street) | 61 | Victor Hugo utca 18-22. |
| 2Connect DC10 | 14 | Kozma utca 2. |
| VIVAnet DC | 4 | Venyige street 5. |
| DoclerNet | 1 | Expo tér 5-7. |
| Pro-M Victor Hugo | 0 | Victor Hugo u 18-22 |
What a Budapest IP address tells you
BIX, the Budapest Internet eXchange, is the only exchange PeeringDB records in the city, and its 103 participants match the 103 peers the registry counts for Budapest as a whole. More network presences sit in colocation than on the exchange, with six facilities holding 145 between them. Dataplex Budapest has 65 and the BIX Building on Victor Hugo street 61, which together account for most of that total. 2Connect DC10 has 14, VIVAnet DC 4 and DoclerNet 1, while Pro-M Victor Hugo records none. Five ASNs on the BIX member list match the mobile carrier registry, which holds no Hungarian operators.
An address that geolocates to Budapest does not put a device in Budapest. An operator announces address blocks from a registry record, and that record carries one address for the whole allocation, often the company's own office. Mobile networks concentrate traffic through a small number of gateways, so a handset elsewhere in Hungary can reach the internet from a block registered in the capital. Geolocation databases follow what the operator publishes, so they repeat the operator's stated location rather than the position of whoever is using the address.
Someone checking an address learns more from the origin ASN and the netname on the specific prefix than from a city label. The origin ASN names the network announcing the block, and the netname often tells you whether the range is fixed broadband or a mobile pool. A reverse DNS name on the address can point to the same answer. PeeringDB does not record any of that per city; it counts networks at exchanges and in facilities, which is what the Budapest figures above describe.
Questions
Which internet exchanges are in Budapest?
PeeringDB records one, BIX (Budapest Internet eXchange), with 103 participants. No second exchange appears for the city. Six colocation facilities sit alongside it, holding 145 network presences, the two fullest being Dataplex Budapest with 65 and the BIX Building on Victor Hugo street with 61.
Do Hungarian mobile carriers peer in Budapest?
The carrier registry lists no Hungarian mobile operators, so it cannot answer that. It does show that five ASNs on the BIX participant list belong to mobile operators recorded in other countries. Whether Hungary's own mobile networks peer at BIX is not something these records confirm.
Does an IP that geolocates to Budapest mean the device is there?
No. The city comes from the operator's registry record for the address block, not from the device. Mobile traffic leaves through a few gateways, so a block registered in Budapest can carry users from anywhere in the country. Check the origin ASN and the prefix netname instead.
