Sunrise: The Sunrise period is for Trademark Holders to protect their rights in the new TLD extension. Anyone with a trademark registered before the Sunrise period begins may apply for domains that are an exact match (or very close to) their trademark.
Landrush: The Landrush period is the limited time opportunity for any customers to place orders for generic domains in the new TLD extension, without any restrictions or documentation. Landrush does not operate on a first-come, first-served basis. Domain names that receive multiple applications during the landrush period will be sent to an auction at the close of the landrush period, with the domain allocated to the winning bidder of the auction.
General Availability: General Availability begins the period in which all remaining domains are available to register on a first-come, first-served basis. There are no restrictions during this period and the domains may be registered at any Registrar that carries the new TLD extension.
