*1:The function to judge the server halt condition can be selected even by "404 Not Found" as an option. This function is very effective in the DDNS environment. If this option is not made effective when Internet Protocol address before other machines that operate the Web server after changing Internet Protocol address of the server change is acquired, the event to which DDNS has not been renewed cannot be detected. Because the unique file cannot be found if it uniquely observes it when this option is made effective URL, DDNS can be detected not being renewed.
