Zusammenfassung:	A method for authenticating a user by IP address check includes: receiving a URL and a session cookie from a client; determining whether or not an IP address of the client has been changed based on the session cookie; resetting the session cookie, if the IP address has been changed, by adding the changed IP address as a temporary IP address thereto; determining whether or not the URL is required to perform IP address check; requesting a re-login to the client if it is determined that the URL is required to perform IP address check; and adding the temporary IP address to a valid IP address list for the user if the re-login is successful.
