What a Saint-Petersburg IP address tells you
PITER-IX Saint-Petersburg is the only exchange PeeringDB records here, and its 247 participants are the city entry's entire peering population. The registry attaches no facility to this record, so there is no colocation network count to set beside the exchange figure, and everything documented sits at the exchange itself. One ASN from the country's mobile carrier registry, AS13194, appears among the participants, which makes PITER-IX Saint-Petersburg the one place in this record where a Russian mobile network is documented as peering.
An address that a lookup places in Saint-Petersburg may belong to a subscriber anywhere the announcing operator carries traffic. The operator registered the block once, with one address on the record, and can route it from any part of its network. Mobile users reach the internet through a small set of gateways, so thousands of sessions share whatever city the gateway's addresses were registered to. Geolocation providers follow the operator's published location, which keeps their answers consistent with each other and detached from where the handset is.
Checking the origin ASN and the netname on the specific prefix answers more than the city field does. AS13194 is the one carrier ASN recorded at PITER-IX Saint-Petersburg, and seeing it as the origin of a prefix tells you a mobile network announced the block, while the netname shows the label its owner assigned. Membership of an exchange with 247 participants says where a network can exchange traffic, not which addresses it hands to a particular customer or where that customer sits.
Questions
Which internet exchanges are in Saint-Petersburg?
PeeringDB records one against this entry, PITER-IX Saint-Petersburg, listed with 247 participants. No other exchange and no colocation facility appears under the same city name, so 247 is the whole of the documented peering count here.
Do Russian mobile carriers peer in Saint-Petersburg?
One does, by the registry's own matching. AS13194 sits among the 247 participants at PITER-IX Saint-Petersburg. Other operators may exchange traffic in the city without publishing it, since PeeringDB records what each network chooses to enter about itself.
Does an IP that geolocates to Saint-Petersburg mean the device is there?
No. The city comes from the address block's registration and from the operator's published location, not from any measurement of the device. A phone connected in another part of Russia can use a gateway whose addresses carry a Saint-Petersburg registration and will look local in every lookup.
