Top-level domain

A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is com. Responsibility for management of most top-level domains is delegated to specific organizations by the Internet Corporation for Assigned Names and Numbers (ICANN), which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone.

You can find the complete list of TLD in the rTLD repository

Generic top-level domains

Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last level of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC:920.

The following domains under the Generic Top-Level domain registry is listed here mainly because we have chosen to block them inside our [Rpz] zones to protect you and the free democracy.

Sponsored top-level domain

A sponsored top-level domain (sTLD) is one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. IANA currently distinguishes 3 groups of top-level domains: (1) country-code top-level domains (ccTLD), generic top-level domains (gTLD) and infrastructure top-level domain.

A sponsored TLD is a specialized top-level domain that has a sponsor representing a specific community served by the domain. The communities involved are based on ethnic, geographical, professional, technical or other theme concepts proposed by private agencies or organizations that establish and enforce rules restricting the eligibility of registrants to use the TLD.

Generally speaking, a sponsored TLD is a specialized TLD that has a sponsor representing the narrower community that is most affected by the TLD, while an unsponsored TLD operates under policies established by the global Internet community directly through the ICANN process. (2)

For example, the .aero TLD is sponsored by SITA, which limits registrations to members of the air transport industry.

ICANN only applied the term sponsored TLD to TLDs in the first two rounds of new [[gTLD]]s. It did not use the distinction between sponsored and unsponsored for new gTLDs in the 2012 round. (3)
