A country code second-level domain is a second-level domain to a country code top-level domain.[citation needed] Such a domain may be reserved by a domain name registry for the registration of third-level domains, or assigned to a third party as a subdomain.

Many country code domain registries implement domain name classes at the second level underneath their ccTLD, such as are present in the original generic top-level domains com, net, and org, which were intended for commercial entities, network operators, and non-profit organizations, respectively.

Many countries implement additional classes. For example, the United Kingdom (uk) uses for commercial purposes and for academic registrants. Brazil (br) has a high number of restricted second-level domains, 67 as of 2011;[1] they range from for commercial activities and for veterinarians to for wikis.[2]
