Second-level domain

In the [Domain Name System] (DNS) hierarchy, a second-level domain (SLD) is a domain that is directly below a [top-level domain] (TLD). For example, in example.com, example is the second-level domain of the .com TLD.

Second-level domains commonly refer to the organization that registered the domain name with a [domain name registrar] . Some [domain name registries] introduce a second-level hierarchy to a TLD that indicates the type of organization intended to register an SLD under it. For example, in the [.uk] namespace a college or other academic institution would register under the .ac.uk [ccSLD] , while companies would register under .co.uk.
