.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.

History

.nic.tr, formerly the official registry's domain, was closed on 12 September 2022. Since then domain management is only possible via accredited registrars. The registry TRABIS is also a registrar but only for restricted SLDs like gov.tr. Additionally com.tr, org.tr and net.tr can be registered without additional documents since this date.

Second-level

The second-level .tr TLD is currently in its launch process. The registry started a 3-phase launch process with different priorities of current SLD registrants to apply for the second level variant. Currently the third and last launch phase is ongoing from 14 February 2024 to 7 August 2024, after which domains will be allocated first-come first-served.

.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 does not have a top-level domain and uses .tr, the top-level domain name of Turkey. 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 44 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.
