Country Code Top Level Domains

There are two types of top-level domains: generic and country code. Generic Top Level Domains (gTLD) are used on a global basis and include tlds like Com, Net, org, Info, biz, Aero, etc.

Country code Top Level Domains (ccTLD) are meant for use by individual countries, as they deem necessary. Examples include .US, .UK, .AU, .IN, etc.

Some country code domains are open to registration on a global basis. However most of the country code domains are restricted.

Whois Servers for ccTLDs

The registries for country code TLDs maintain their own whois servers. Here are a few examples

UK: whois.nic.uk
US: whois.nic.us
ca: whois.cira.ca
de: whois.nic.de
ws: whois.nic.ws
au: whois.aunic.net
in: whois.inregistry.net
nu: whois.nic.nu
