The MyWebServer Address Monitor program monitors your dynamic IP address as often as every five minutes, and updates your MyWebServer 'VDNS Redirector Page' every time your IP address is changed by your ISP. This reduces the amount of time your server is 'Un Available' after an address change. The Address Monitor is not necessary if you do not use the MyWebServer VDNS Redirector or if you use a Dynamic Addressing Service like. ICQ, dyndns or DNS2Go etc.
