Internet exchanges in Warsaw
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.

What a Warsaw IP address tells you
Warsaw carries 1,146 exchange participants across five peering fabrics. EPIX.Warszawa holds 378 of them and TPIX PL 333, so most of the local peering sits on those two rather than on THINX Warsaw with 148 or Giganet IXN Warsaw with 48. Colocation carries a comparable weight. LIM Warsaw records 256 networks, Equinix WA1 at Centrum LIM 248, and ATMAN Data Center Warsaw-2 65, out of 811 network presences across 21 facilities. Two of Poland's mobile operators peer here, T-Mobile Polska on AS12912 and Play on AS39603, both at Equinix Warsaw.
An address that geolocates to Warsaw is not evidence of a device in Warsaw. Orange Polska, Play and T-Mobile Polska register address blocks against a company record and announce them from AS5617, AS39603, AS201019 and AS12912 whatever cell a handset attaches to. Mobile traffic leaves through a small number of gateways, so subscribers hundreds of kilometres apart can share one prefix. Geolocation databases follow the operator's own published location for that block, which for a national carrier is usually the head office rather than the cell site.
Someone checking a Warsaw address should read the origin ASN and the netname on the specific prefix rather than a city label. AS5617, AS12912, AS39603 and AS201019 mark Polish mobile networks, while an origin belonging to one of the networks colocated at LIM Warsaw or ATMAN points at a hosted machine instead. The registry entry for the exact prefix, its size and its holder say more about what sits behind the address than any city name. PeeringDB itself records where networks connect, never where end users are.
Mobile carriers in Poland
A mobile address in Warsaw is routed by one of the country's operators. Each entry lists the operator's ASNs, so you can check which network an address belongs to.
Questions
Which internet exchanges are in Warsaw?
PeeringDB lists five. EPIX.Warszawa has 378 participants, TPIX PL 333, Equinix Warsaw 239, THINX Warsaw 148 and Giganet IXN Warsaw 48. Together they account for 1,146 participant records, and a single network can and often does appear on more than one of them.
Do Polish mobile carriers peer in Warsaw?
Two of the three in the registry do. T-Mobile Polska (AS12912) and Play (AS39603) are both listed at Equinix Warsaw. Orange Polska's mobile AS5617 is not recorded on any Warsaw exchange in this snapshot, which does not rule out private interconnection that PeeringDB never sees.
Does an IP that geolocates to Warsaw mean the device is there?
No. It means a database associates the address block with Warsaw, usually because the operator published that location in its registry record. The handset can be anywhere the carrier has coverage, because mobile traffic exits through a small number of gateways.
