You can get the IP Address of the server, then do a reverse DNS. All this can be done by pinging the website (then you will get the IP Address) and then using the reverse DNS tool to resolve IP Addresses into hostnames.

Once you get the hostname, you should know what name the hosting company goes by. It would only work if the hosting company has a reverse DNS entry, though.
