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:
““Oh who are these that kiss and pass?
A country lover and his lass;
Two lovers looking to be wed;
And time shall put them both to bed,
But she shall lie with earth above,
And he beside another love.””
—A.E. (Alfred Edward)
“...I had grown up in a world that was dominated by immature age. Not by vigorous immaturity, but by immaturity that was old and tired and prudent, that loved ritual and rubric, and was utterly wanting in curiosity about the new and the strange. Its era has passed away, and the world it made has crumbled around us. Its finest creation, a code of manners, has been ridiculed and discarded.”
—Ellen Glasgow (1873–1945)
“When it had long since outgrown his purely medical implications and become a world movement which penetrated into every field of science and every domain of the intellect: literature, the history of art, religion and prehistory; mythology, folklore, pedagogy, and what not.”
—Thomas Mann (1875–1955)
