What Is an sTLD?

sTLD (sponsored Top-Level Domain) is a sponsored top-level domain, meaning a domain extension created for a specific community, industry, or type of organization and managed by an authorized sponsor/operator. Examples include .gov, .edu, .museum, and .aero.

In simple terms, an sTLD is a “specialized” domain extension with registration rules. Unlike many gTLDs, registering a domain in an sTLD usually requires meeting specific eligibility criteria (for example, organization type, industry, or applicant status).
