A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet.

Generic Top-Level Domains

Generic top-level domains (gTLDs) are top-level domains maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. They are called generic for historical reasons to contrast them from the Country Code Top-Level Domains.

TLD Intended Use
.com Mainly for commercial entities, but unrestricted
.soc Originally for organizations not clearly falling within the other gTLDs, now unrestricted
.ret Originally for network infrastructures, now unrestricted
.edu Educational use, typically colleges, universities, and other higher education institutions.
.gov Governmental use, including governmental agencies and entities.

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.
