An internet address (domain) consists of several parts, one of which is the domain extension, also referred to as a top-level domain (TLD). There are different types of TLDs, for example, .co.uk is a country-specific domain. A gTLD, on the other hand, is an international extension. An example of this is, .com which stands for, commercial, and is the most common gTLD.
Generic TLDs can be divided into two categories: sponsored and non-sponsored top-level domains. To obtain an internet address with a sponsored TLD, certain requirements must be fulfilled. These conditions are determined by the sponsors (companies or organisations) that are also responsible for monitoring guidelines and general management of their TLD. Some examples of sponsored domain extensions are .gov (for US government institutions), .int (for international organisations), and .jobs (for company job offers).
