About .gu domains

About .gu domains

.GU is a country-code top-level domain (ccTLD) in the DNS root zone. It is designated for Guam. The IANA root zone lists the registry manager as University of Guam. Registration policies (who may register, local presence, pricing) are set by the registry and its accredited registrars — not by IANA.

.gu is the Internet country code top-level domain (ccTLD) for Guam. Registrations are free of charge but are limited to people or companies with a contact in Guam, and are limited to third-level registrations beneath second-level names such as .com.gu. There has not been very much use of .gu addresses.

Who can register .gu domains?

Eligibility is defined by the registry operator and its registrars. Most gTLDs are open to anyone worldwide. Many ccTLDs are also open globally; some require local presence, citizenship, or trademark rights. Always confirm current policy with the registry or your registrar.
