.tr is the Internet country code top-level domain (ccTLD) for Turkey. It is administered by trABİS (under the Information and Communication Technologies Authority of Turkey) and managed by the Computer Center DNS Group of the ICT Authority. The domain was formerly administered by NIC.tr and managed by the Turkey Internet Society (the local chapter of ISOC) until September 2022.

Statistics

As of March 2017, around 15.53% of all the .tr domains were served via secured HTTPS protocol, with the Let's Encrypt Authority X3 being the most popular SSL certificate. Microsoft-IIS is the most popular web server, serving 35.31% of the .tr domains, followed by Apache serving 35.14% of the total .tr domains.

Domains

Second-level

nic.tr
nic.tr, formerly the official registry's domain, is one of the two second-level domains under this TLD. However, current registry TRABIS states that, restricted registrations directly at the second level will start one year after their incorporation date, which is 14 September 2022.

ct.tr and nc.tr
ct.tr and nc.tr are the second level domain names of Northern Cyprus. Because Northern Cyprus is a unrecognised state, it can not have a top-level domain. Because of this, second level domain names were created with the .tr extension, which is the top-level domain name of Turkey. For now, the infrastructure has been created for the future spread of the domain names, which only hosts the websites of some Turkish Cypriot state institutions. ct.tr hosts 33 websites, while nc.tr is never used except for two websites, one of which is a duplicate version of the Republican Assembly's ct.tr version. That has two versions: One that has https, which is expired, and one without it, which is faster than the ct.tr version. The other website is the searching feature of the Republican Assembly.
