ICANN requires a Sunrise of at least 30 days and a Claims period of at least 90 days. But a registry might choose for additional stages: a second or even third Sunrise, a Landrush, a silent period, and maybe even more. Information about the different stages of a registry will be published shortly before a registry will launch its TLD.
The stages can be described as follows;
During the Sunrise trademark owners can submit their registrations. To submit a domain during Sunrise a TMCH registration is required. Often the domain will not immediately be registered on your behalf, but the registry may gather all requests and have an auction at the end of the Sunrise period if multiple applications exist for the same name.
During the Landrush anyone can submit a request for a specific domain. Just like the Sunrise the domain will usually not be immediately registered, but auctioned at the end of the Landrush period.
During the General Availability period anyone can submit a registration for the TLD. These registrations will usually be processed immediately and the owner can start using it right away. During the first 90 days of a TLDs existence there will also be a Claims period. During this time trademark holders will be notified if a registered term is registered as a domain name. Please note that we will request explicit approval from the Registrant if a registered trademark is found, informing the Registrant of the trademark.
During the General Availability phase the domains can not be transferred, only after this period will the domains be free to transfer to any Registrar you may wish.
