About .one domains

About .one domains

.ONE is a generic top-level domain (gTLD) delegated in the DNS root zone. The registry operator responsible for .ONE is listed by IANA as One.com A/S. Anyone can typically register a .ONE name through an accredited registrar, subject to the registry’s registration policy and ICANN consensus policies.

.one is a top-level domain. It was proposed in ICANN's New generic top-level domain (gTLD) Program, and became available to the general public on May 20, 2015. One Registry and ARI Registry Services are the registries for the domain.

Who can register .one 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.
