Novosibirsk · Russia
PeeringDB records two exchanges in Novosibirsk. MSK-IX Novosibirsk holds 41 of the city's 44 participant records and PITER-IX Novosibirsk the remaining three. Four facilities report 23 networks, 18 of them at Sinar. An address geolocating to Novosibirsk points to how an operator registered the block, not to a device in the city.
Internet exchanges in Novosibirsk
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 |
|---|---|---|
MSK-IX Novosibirsk MSK-IX Novosibirsk (former NSK-IX) | 41 | none in the registry |
PITER-IX Novosibirsk | 3 | none in the registry |

What a Novosibirsk IP address tells you
Almost all of Novosibirsk's recorded peering sits at one exchange. MSK-IX Novosibirsk lists 41 participants against PITER-IX Novosibirsk's three, and those 44 records are the city's whole documented total. Colocation adds less than the exchanges do, with four facilities reporting 23 networks. Sinar holds 18 of them, Nextremum NSK-1 and KeyPoint Novosibirsk two each, and Adman one. Neither exchange has a carrier ASN attached in the registry, so it documents no Russian mobile network peering here.
An address that a database places in Novosibirsk need not sit in Novosibirsk. The operator that announced the block registered it once, with one address for the whole allocation, and can route the range from any point in its network. Mobile traffic leaves through a small number of gateways, so subscribers spread across a wide area share the location attached to the gateway's addresses. Providers of geolocation data read the operator's published record and reproduce it, which makes their answers uniform rather than accurate about a particular device.
Someone checking an address should read the origin ASN and the netname on the exact prefix. Those two fields name the network that announced the range and the label its owner registered, which is closer to the truth than a city string that 44 participant records and four facilities cannot confirm. A network present at MSK-IX Novosibirsk may announce addresses used far from the city, and a network absent from PeeringDB may still carry traffic through it.
Questions
Which internet exchanges are in Novosibirsk?
PeeringDB lists two, MSK-IX Novosibirsk with 41 participants and PITER-IX Novosibirsk with three. Together they account for the 44 participant records held against the city. Private interconnection inside Sinar or the other three facilities does not appear in that count.
Do Russian mobile carriers peer in Novosibirsk?
None is recorded. The registry attaches no carrier ASN to MSK-IX Novosibirsk or PITER-IX Novosibirsk. That reflects what operators published about themselves, and a mobile network can route through the city without listing a presence at either exchange.
Does an IP that geolocates to Novosibirsk mean the device is there?
No. The city label follows the registration on the address block and the location the operator published for it. Sessions from elsewhere in Russia can exit through gateways whose addresses carry a Novosibirsk registration and will be reported at that location.
