.tr is the Internet country code top-level domain (ccTLD) for Turkey. It is administered by NIC.TR (under Middle East Technical University) Computer Center and Turkey Internet Society (Local Chapter of ISOC). .nc.tr and .ct.tr are used as second-level domains for the Turkish Republic of Northern Cyprus, which is a self declared state and not recognised by the United Nations, and as such has no country code assigned.


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.[2] 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.[2]



nic.tr, the official registry's domain, is the only second-level domain under this TLD; other second-level domains are prohibited.
