St. Petersburg · Russia
PeeringDB records four exchanges in St. Petersburg, and MSK-IX Saint-Petersburg has the most participants at 60. Colocation is the heavier side of the record, with 20 facilities holding 318 network presences and Bolshaya Morskaya 18 counting 62. An address geolocating here shows an operator's registration, not a device on a St. Petersburg street.

What a St. Petersburg IP address tells you
The four exchanges under St. Petersburg add up to 93 participant records, with MSK-IX Saint-Petersburg holding 60, CLOUD-IX SPB 25, PIRIX six and CODIX two. Colocation carries more of the city's presence than the exchanges do, with 20 facilities reporting 318 networks between them, Bolshaya Morskaya 18 at 62, Raduga-2 at 58 and Tsvetochnaya Data Center at 47. The registry attaches no carrier ASN to any of the four exchanges, so it documents no Russian mobile operator peering in the city.
An address that resolves to St. Petersburg tells you how a block was registered, not where the equipment sits. An operator files one location for an allocation that may cover subscribers across several regions, then announces the prefix from wherever its routing terminates. Mobile sessions leave through a handful of gateways, and a gateway in one city can serve users hundreds of kilometres away. Databases take the location the operator published and copy it forward, which is why lookups agree with each other and can still be wrong about the device.
The origin ASN and the netname on the exact prefix carry more information than the city field. The ASN identifies the network that announced the block, and the netname is the operator's own label for that range, which sometimes names a region or a customer. Neither says whether the traffic ever crossed MSK-IX Saint-Petersburg or sat in one of the 20 facilities on record, because PeeringDB documents where networks interconnect and routing data documents who holds an address.
Questions
Which internet exchanges are in St. Petersburg?
PeeringDB lists four under this city entry. MSK-IX Saint-Petersburg has 60 participants, CLOUD-IX SPB 25, PIRIX six and CODIX two. Networks that peer privately inside a facility rather than at an exchange do not appear in those counts.
Do Russian mobile carriers peer in St. Petersburg?
The registry attaches no carrier ASN to MSK-IX Saint-Petersburg, CLOUD-IX SPB, PIRIX or CODIX. That is silence in the record rather than evidence that mobile networks carry no traffic through the city's 20 facilities, since operators publish their presences voluntarily.
Is more of St. Petersburg's capacity in exchanges or facilities?
By the counts PeeringDB holds, in facilities. The four exchanges total 93 participant records, while 20 facilities report 318 network presences, with Bolshaya Morskaya 18 at 62 and Raduga-2 at 58 at the top. A network can appear in both figures.
