A '''country code second-level ___domain''' is a [[second-level ___domain]] to a [[country code top-level ___domain]].{{citation needed|date=December 2010}} Such a ___domain 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 ___domain]]s <tt>com</tt>, <tt>net</tt>, and <tt>org</tt>, 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|uk]]) uses <tt>[[.co (second-level ___domain)|co.uk]]</tt> for commercial purposes and <tt>[[.ac (second-level ___domain)|ac.uk]]</tt> for academic registrants.

Brazil ([[.br|br]]) has a high number of restricted second-level domains, currentlyas of 2011<ref>[http://registro.br/info/dpn.html Registro.br] 4 February 2011</ref> amounting to 67; they range from <tt>com.br</tt> for commercial activities, <tt>vet.br</tt> for veterinarians, to <tt>wiki.br</tt> for wikis.<ref>[http://registro.br/info/dpn.html Registro.br - Categorias .br, Brazil registry information]</ref>
