摘要：
An apparatus receives an address for use in communication with an external apparatus and a lease period of the address. When the apparatus is switched into a state where the amount of electric power provided to the apparatus is reduced, the apparatus determines whether the address is valid based on the lease period of the address. If the address is valid, the apparatus carries out communication using the received address.
