To register a domain name in a country code TLD
(such as .uk or .jp), please contact the corresponding ccTLD registry:
http://www.iana.org/cctld.html.
Registering your domain name under a ccTLD warrants further investigations
on the registry legitimate authority and on the namespace delegation policy.
Please note that ccTLD's policies vary and check the following:
in which country a ccTLD registry is located
in which country a ccTLD registry is incorporated (if private company)
