Use a wildcard that is setup hosting for *.xtool.com then in the scripting language, e.g. PHP, just look for the host name, should allow you an unlimited number of subdomains which your scripts can process. If you only have a limited number of subdomains then just set them all up pointing to the same folder, again in the scripting language just look for the host name.
