Country Code Second-level Domain

A country code second-level domain (ccSLD) is a second-level domain to a country code top-level domain. 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) has a high number of restricted second-level domains, currently amounting to 67; they range from com.br for commercial activities, vet.br for veterinarians, to wiki.br for wikis.

Famous quotes containing the words country, code and/or domain:

    There is a city myth that country life was isolated and lonely; the truth is that farmers and their families then had a richer social life than they have now. They enjoyed a society organic, satisfying and whole, not mixed and thinned with the life of town, city and nation as it now is.
    Rose Wilder Lane (1886–1965)

    Acknowledge your will and speak to us all, “This alone is what I will to be!” Hang your own penal code up above you: we want to be its enforcers!
    Friedrich Nietzsche (1844–1900)

    In the domain of Political Economy, free scientific inquiry meets not merely the same enemies as in all other domains. The peculiar nature of the material it deals with, summons as foes into the field of battle the most violent, mean and malignant passions of the human breast, the Furies of private interest.
    Karl Marx (1818–1883)
