A country code second-level ___domain (ccSLD) is a second-level ___domain to a country code top-level ___domain.[citation needed] A ccSLD may be reserved by the ___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 as well. For example, the United Kingdom (uk) uses co.uk for commercial purposes and ac.uk for academic registrants.
Brazil (br) is probably the country with the highest number of restricted second-level domains, currently[when?] amounting to 66; they range from com.br for commercial activities, vet.br for veterinarians, to wiki.br for wikis.[1]
