Türkiye's internet in numbers

Four questions that sound alike

The figures above answer different questions, and the numbers differ because of it. None of them proves where a particular person or device is.

Registered in Türkiye

The registry (RIPE NCC) lists the holder of the block with country code TR. It says who holds the addresses, not where they are used.

Geolocated to Türkiye

A geolocation database (here DB-IP Lite) estimates that the block is used in Türkiye. Blocks registered elsewhere can be geolocated here, and Turkish-registered blocks can be used abroad.

Announced by a Turkish network

A network whose AS number is registered in Türkiye originates the route in BGP. Turkish networks announce more address space than is registered here, because they also route blocks transferred to them or registered to customers elsewhere.

Physically in Türkiye

Where the equipment or the person actually is. No public dataset can establish this for an address; only the network operator knows.

Turkish networks by announced IPv4 space

AS numbers registered to organisations in Türkiye, ranked by the IPv4 address space they originate in our copy of the BGP table. The names are those in the registry; one operator often runs several AS numbers (fixed, mobile, enterprise), so Türk Telekom, Turkcell and Vodafone each appear more than once.

Where Turkish IPv4 addresses are estimated to be used

IPv4 addresses that DB-IP Lite places in Türkiye, summed per province and per geographical region. This is a location estimate for address blocks, usually where the provider's equipment or office is, not where people live.

By geographical region

• Marmara59.3%
• Central Anatolia19.6%
• Aegean7.7%
• Mediterranean5.2%
• Black Sea4.4%
• Southeastern Anatolia2%
• Eastern Anatolia1.9%

DB-IP labels Turkish ranges with the 81 provinces, in mixed spellings (“Istanbul”, “İzmir Province”, “Canakkale”); they are folded to the official Turkish name and nothing else is changed. Ranges the source assigns to another country code are not counted here. İstanbul and Ankara weigh far more than their population because the large operators run their core networks, data centres and head offices there; a province with a small share is not a province with few internet users.

Where Turkish networks meet

Networks exchange traffic directly at internet exchange points (IXPs) instead of carrying it through a third party. Türkiye's public exchanges are young and concentrated in İstanbul; much domestic traffic still flows over private interconnections between the large operators, which no public registry lists.

Source: PeeringDB, checked 7 Nov 2026: all 6 exchanges listed in Türkiye. PeeringDB lists 50 data centres in Türkiye; counted by the province in their postal code, İstanbul has 29 and Ankara 8.

Who does what

• RIPE NCC

  The regional internet registry for Europe, the Middle East and Central Asia, based in Amsterdam. It allocates IPv4 and IPv6 blocks and AS numbers to Turkish operators and publishes who holds them, over RDAP and in its daily delegation file.

• BTK

  Bilgi Teknolojileri ve İletişim Kurumu, the Information and Communication Technologies Authority, licenses and regulates electronic communications in Türkiye, including fixed and mobile operators. It is also the authority responsible for the .tr country-code domain. It does not allocate IP addresses.

• TRABİS

  The .tr domain registry system, run under BTK since 14 September 2022, when it replaced the nic.tr service operated by METU since 1991. Registrations go through accredited registrars; registration data is published over port-43 WHOIS (whois.trabis.gov.tr). IANA's RDAP registry lists no RDAP server for .tr.

• TÜBİTAK ULAKBİM

  Runs ULAKNET, the national research and education network that connects Turkish universities and research institutions (AS8517), and the TR-GRID and academic services built on it.

• USOM

  Ulusal Siber Olaylara Müdahale Merkezi, Türkiye's national computer emergency response team, set up within BTK. It takes incident reports and publishes security notices and lists of malicious addresses and domains.

• KVKK

  The Personal Data Protection Authority enforces Law No. 6698 on the Protection of Personal Data. An IP address can be personal data when it can identify a person together with other data; the Authority publishes guidance on cookies and online tracking.
