Restricted Extensions

Sponsored Top-Level Domains (sTLDs)

Sponsored TLDs are specialized domain extensions managed by specific organizations or communities with defined eligibility requirements. Unlike open gTLDs, these extensions like .edu, .gov, and .museum serve particular sectors and require verification before registration. They provide instant credibility and trust within their respective communities.

Understanding Sponsored TLDs

Domain extensions with strict eligibility for specific communities.

Sponsored Top-Level Domains are a special category of extensions where a sponsoring organization establishes and enforces rules for registration eligibility. These sponsors represent specific communities and ensure that only qualified entities can obtain domains under their TLD.

The sponsorship model provides several benefits: it maintains the integrity and trustworthiness of the namespace, ensures domains are used for their intended purpose, and creates instant recognition of the registrant's credentials. When you see a .edu website, you immediately know it belongs to an accredited educational institution.

Sponsored TLDs include some of the original domain extensions created in 1985 (.edu, .gov, .mil) as well as newer additions like .museum (2001), .aero (2001), and .coop (2001). Each operates under different policies set by their respective sponsors.

FAQ

No. The .edu domain is restricted to accredited post-secondary US educational institutions only. It's managed by EDUCAUSE and requires proof of regional or national accreditation.

Restrictions maintain trust and credibility. When users see a .edu or .gov site, they know it's legitimate. Open registration would undermine this trust and enable abuse.
