Una vez ha expirado un dominio, puedes hacer backorder desde las diferentes plataformas que existen para ello. Si varias personas han realizado un backorder, entre todas ellas se realiza una subasta. Las diferentes plataformas suelen avisarte (de diferente forma) de que se inicia la subasta, para que estés al corriente de ella.
