    Try opening the URL in your browser it's working. Or use $host good to find the Ip address of the server

      > Try opening the URL in your browser it's working. As the parent said, browsers try to fix bad domains by themselves. > $host good to find the Ip address of the server NXDOMAIN. if you get something else, your DNS provider is injecting something.
