A '''country code second-level ___domain (ccSLD)''' is a [[second-level ___domain]] to a [[country code top-level ___domain]].{{citation needed|date=December It2010}} Such a ___domain may be set apartreserved by thea [[___domain name registry]] for the registration of third-level domains, or registeredassigned 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 {{mono|com}}, {{mono|net}}, and {{mono|org}}, which were intended for commercial entities, network operators, and non-profit organizations, respectively.

Many registries reuse common [[top-level ___domain]] names at the second-level such as "com", "net" and "org", e.g. <tt>[[.com.sg]]</tt>.

Many countries implement additional classes. For example, the [[United Kingdom]] ([[.uk]]) uses {{mono|[[.co.uk|co.uk]]}} for commercial purposes and {{mono|[[.ac.uk|ac.uk]]}} for academic registrants. Brazil ([[.br]]) has a high number of predefined second-level domains, 140 as of 2021; they range from {{mono|com.br}} for commercial activities and {{mono|vet.br}} for veterinarians to {{mono|wiki.br}} for wikis (see [[.br#Second-level_domains|.br § Second-level domains]]).<ref>{{ cite web | url=https://registro.br/dominio/categorias/ | title=Categorias de domínios .br | lang=pt-br | trans-title=Categories of .br domains | website=Registro.br | access-date=17 August 2021 }}</ref>
