What these records establish

This page groups the saved exchange and facility records for Madrid. 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.

Mobile carriers in Spain

These selected carrier records provide ASN references for further checks. They do not establish that a particular address is mobile or that a subscriber is in this city.

Questions

How many exchanges and facilities are recorded in Madrid?
7 exchanges and 21 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 Madrid 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.

These records describe where networks interconnect. A Madrid IP address does not show that a device is in Madrid: mobile carriers route traffic from wide areas through shared gateways, and geolocation databases estimate from registration data.
