A type of an access to a server, which is assigned to a user terminal as a server which provides a service to the user terminal in accordance with an access from the user terminal, is acquired, and it is judged whether or not the type is a prescribed type. When a frequency of judgment of “prescribed type” in the judgment is higher than a prescribed frequency, an apparatus which executes the assignment is set so as not to assign the server to the user terminal from the next time.
