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:
“The filth and noise of the crowded streets soon destroy the elasticity of health which belongs to the country boy.”
—Rutherford Birchard Hayes (18221893)
“Wise Draco comes, deep in the midnight roll
Of black artillery; he comes, though late;
In code corroborating Calvins creed
And cynic tyrannies of honest kings;
He comes, nor parlies; and the Town, redeemed,
Gives thanks devout; nor, being thankful, heeds
The grimy slur on the Republics faith implied,
Which holds that Man is naturally good,
Andmoreis Natures Roman, never to be
—Herman Melville (18191891)
“You are the harvest and not the reaper
And of your domain another is the keeper.”
—John Ashbery (b. 1927)
