.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, as it has no country code assigned.
Other 2nd level domains:
Initially, nic.tr, the official registry's domain, was the only 2nd level domain under this TLD and other 2nd level domains were prohibited. However, recently tsk.tr is registered as a second level domain. The local registry seems to have amended its policy to allow for 2nd level domains, and browsers should update their handling algorithms for this TLD accordingly.
