Changes

Some countries restrict the second level under their [[ccTLD]]. These countries require that the second-level domain be one of several pre-determined second-level domains, generally indicating what type of individual or organization may register under that SLD. For these countries, you are not permitted to register domain names under the top level domain. It must be registered under one of the pre-determined second-level domains, called a ccSLD, or Country Code Second Level Domain.<ref>[http://www.quackit.com/domain-names/second-level_domain_names.cfm Second-Level Domain Names, quack-it.com]</ref>

An example of this would be .co.uk, where .uk is the (cc)TLD and .uk is the (cc)SLD. In this circumstance, the domain name ("example" in "example.co.uk") would be considered the third level domain, as it is in the third position.<ref>[http://www.igoldrush.com/reference/domain-glossary/c/ccsld-country-code-second-level-domain iGoldrush Domain Glossary]</ref> This can become confusing, as the domain name is commonly equated with the second level domain, and the [[subdomain]] is commonly equated with the third level domain. In these circumstances, the third level domain is sometimes referred to as a '''functional SLD'''.<ref>[http://tools.ietf.org/html/draft-ietf-provreg-dn-defn-00 Domain Name and Related Definitions, ietf.org]</ref>
