What these records establish
This page groups the saved exchange and facility records for Kolkata. A sum of participant or facility counts is not a count of unique networks, traffic volume, available capacity or service coverage.
PeeringDB is user-maintained. Its records describe reported interconnection infrastructure; they do not trace a particular request or locate a subscriber. A missing record in this snapshot is not proof that an operator has no presence or private connection in the area.
An IP geolocation result is a separate estimate. MaxMind documents accuracy limits and explains that its location data cannot identify a specific household, person or street address. This registry does not perform a geolocation lookup or measure where an individual device is located.
Questions
- How many exchanges and facilities are recorded in Kolkata?
- 6 exchanges and 11 facilities appear in the 2026-09-07 snapshot. The tables show the saved records and link to the publisher for current details.
- Are the totals unique networks?
- No. Participant entries are summed across exchanges and network presences across facilities. A network listed at several locations contributes to several entries.
- Does a Kolkata IP label prove that a device is there?
- No. These infrastructure records do not establish a device location. Consult the geolocation provider’s accuracy information and the specific network record for the claim you are evaluating.

PeeringDB supplies the exchanges, participant counts, facilities and network presence (snapshot 2026-09-07); MaxMind documents the limits of IP geolocation; the PROXIES.SX carrier registry supplies the operator ASNs used to match peering participants.
These records describe where networks interconnect. A Kolkata IP address does not show that a device is in Kolkata: mobile carriers route traffic from wide areas through shared gateways, and geolocation databases estimate from registration data.
