The change of the nameservers is carried out through the Automated System at https://www.nic.cy  by submitting at least two (2) nameservers in the Fully Qualified Domain Name format. Please, follow the procedure outlined here.

Important Note:

If the nameservers to be recorded have .cy extension, then the IP addresses of these nameservers must also be recorded.  The IP addresses must be different for each nameserver.
