A communication device including a registration unit that registers an IP address of the communication device and a method information including a first method information indicating a first setting method for setting a dynamic IP address and a second method information indicating a second setting method for setting a static IP address. The registration unit includes a change unit that changes registered contents of a memory in accordance with a user's instruction. When the first method information and a first IP address are registered in the memory, the change unit does not change the method information in the memory from the first method information to the second method information in a case where a method change instruction for changing the first setting method to the second setting method is given by the user under a state where the first IP address has not been changed to another IP address.
