What a Tallinn IP address tells you
Peering in Tallinn concentrates in two exchanges. PITER-IX Tallinn carries 68 participants and RTIX, the Tallinn Governmental Internet Exchange, carries 44, while TLLIX and IIX Estonia stay small with 6 and 4. Colocation holds a similar weight. Seven facilities record 80 network presences between them, and Telia Telehouse KJJ with 29 networks and INFONET DC with 27 account for most of those. Two Estonian mobile operators show up in the exchange data. Tele2 Eesti (AS1257) and Elisa Eesti (AS2586) both peer at RTIX, while Telia Eesti's mobile ASNs, 3249 and 16014, appear in none of the four exchange records.
An address that geolocates to Tallinn need not sit on a device in Tallinn. An operator announces a block from one registry record that can cover a whole country, and the 122 networks the registry counts peering in the city tell you nothing about where their customers sit. Mobile traffic leaves a carrier network through a small set of gateways, so a phone anywhere in Estonia can reach the internet from an address the operator anchors in Tallinn. Geolocation databases mostly copy the location the operator publishes for the block, which is often the company's own registered address.
Someone checking a Tallinn address should read the prefix rather than the city label. The origin ASN says which network announces it, and in Estonia that separates Tele2 Eesti (AS1257), Elisa Eesti (AS2586) and Telia Eesti (AS3249 and AS16014) from the hosting and colocation networks that sit in facilities such as Telia Telehouse KJJ or INFONET DC. The netname on the specific prefix tells you which of the two you have, and whether the block is mobile access space or something announced from a rack.
Mobile carriers in Estonia

Questions
Which internet exchanges are in Tallinn?
PeeringDB records four exchanges in Tallinn. PITER-IX Tallinn has 68 participants, RTIX, the Tallinn Governmental Internet Exchange, has 44, TLLIX has 6 and IIX Estonia has 4. PITER-IX Tallinn is the best connected of the four by participant count.
Do Estonian mobile carriers peer in Tallinn?
Two do, according to the exchange records. Tele2 Eesti (AS1257) and Elisa Eesti (AS2586) both peer at RTIX. Telia Eesti's mobile ASNs, 3249 and 16014, are not recorded at any of the four exchanges, which does not rule out private interconnection inside a facility.
Does an IP that geolocates to Tallinn mean the device is there?
No. The city label comes from the address block's registry record and from what the operator publishes, so it points at the network, not at a handset or a server. A mobile address anchored in Tallinn can carry traffic from a device anywhere in Estonia. Check the origin ASN and the netname on the prefix instead.
