How do I find out the host of an existing website?

If you are currently a paid Internet subscriber, you are entitled to a "homepage" which often contains simple navigation and editing tools. And if you use the Netscape browser, the built-in Composer feature is a superior HTML authoring tool. You can easily generate a full-blown website as a Homepage. Nevertheless, the "homepage" URL is likely to be "http://homepage.earthlink.com/subscribe... name" and that URL can easily be overwritten via a redirection service, i.e., "mydomain.com" which allows you to link any registered domain name to "mask" another website. For example, should you type in "domainname.com", you will be immediately transported to the homepage and the hompage URL of http://homepage.earthlink.com/subscriber... name will be masked by the domainname.com. And the charge for the redirection service [even at godaddy.com] is normally FREE. Here's a demonstration: Type in the URL window: "www.pizzanextdoor.com" which will bring up their pizza website. Take note of the domain name. Then type in the URL window: "http://home.pacbell.net/vten/1a/pizzame... and you will see that this is the original homepage which is unmasked without the domain name! Good luck!

http://www.whois.sc/ Also works. Here is more information about whois lookup tool. WHOIS is a TCP-based query/response protocol which is widely used for querying a database in order to determine the owner of a domain name, an IP address, or an autonomous system number on the Internet. WHOIS lookups were traditionally made using a command line interface, but a number of simplified web-based tools now exist for looking up domain ownership details from different databases. Web-based WHOIS clients still rely on the WHOIS protocol to connect to a WHOIS server and do lookups, and command-line WHOIS clients are still quite widely used by system administrators. http://en.wikipedia.org/wiki/Whois
