.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.
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.
It is also used in many Team Fortress 2 based websites such as scrap.tf.
