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 organizations) 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 organizations), and .jobs (for company job offers).
The non-sponsored TLDs, on the other hand, are monitored and managed centrally. ICANN Internet Corporation for Assigned Names and Numbers) is primarily responsible for these and works together with various partners. When the first non-sponsored TLDs were introduced, it was originally planned for them only to be purchased under certain conditions. Like sponsored gTLDs, they should denote a clear frame of reference for websites: .com was initially only available for companies, .net was intended for internet service providers, and .pro for professional use in various occupations. These plans, however, were gradually dropped and now almost every non-sponsored gTLD is available for individuals, businesses, organizations, etc. to use.
