About .hm domains

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

.hm is the Internet country code top-level domain (ccTLD) of the Heard and McDonald Islands, uninhabited islands in the southern Indian Ocean under the sovereign control of Australia. The .hm registry was added in July 1997. The Australian government, the only entity with any formal ties to the territory, does not use the domain, instead using .au, the domain for Australia, for the islands' official website. An Australian registrar, the HM Domain Registry (registry.hm), manages the domain and has opened it to outside registration. Any entity can register an .hm domain, with all domains directly registered at the second level. The domain zone is being used by several websites related to Khanty-Mansiysk (Russia). Examples are a local engineering company Istok and Avto HM VK group's short link.

Who can register .hm 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.
