i am accessing my wamp server from WAN through PC's IP address 122.xxx.xxx.xx. but now i want to access my wamp through DOMAIN name. i only have my domain name and no other credentials for setting. is it possible with domain name?
You need to point your domain name at that ip address. In your settings or admin panel where you setup/purchased your domain name set the ip address to the 122.xxx.xxx.xx you have been using.
