.tr is the Internet country code top-level domain (ccTLD) for Turkey. It is administered by Middle East Technical University Computer Center. .nc.tr is used as a second-level domain 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. 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.
Other second-level domains
Initially, nic.tr, the official registry's domain, was the only second-level domain under this TLD and other second-level domains were prohibited. However, recently tsk.tr is registered as a second-level domain.
