A country code second-level domain (ccSLD) is a second-level domain to a country code top-level domain. It may be set apart by the domain name registry for the registration of third-level domains or registered to a third party as a subdomain.

Many registries reuse common top-level domain names at the second-level such as "com", "net" and "org", e.g. .com.sg.

Other countries have their own second-level names. For example, United Kingdom (.uk) has .co.uk (commercial) and .ac.uk (academic).

Brazil (.br) is probably the country with the highest number of restricted second-level domains,[1] currently amounting to 66; they range from .com.br for commercial activities, .vet.br for veterinarians, to .wiki.br for wikis.[2]
