In a Start-Date Sunrise, a Registry Operator may allocate or register domain names on a first-come, first-served basis or any other time-based allocation or registration process, in addition to any other manner of allocation or registration they desire. In an End-Date Sunrise, a Registry Operator must not allocate or register domain names prior to the end of the Sunrise Period and must not employ a first-come, first-served or any other time-based allocation or registration process.
