Configure a Host Header for a Web Site (IIS 7)

Host headers (also known as domain names or host names) let youassign more than one site to a single IP address on a Web server.

Note   Host headers work for HTTP 1.1-compliant browsers (Internet Explorer 3.x and later, or Netscape Navigator 3.x and later).

Tohost more than one Web site on a Web server, you can assign a unique IPaddress to each Web site, designate a non-standard TCP port number fora Web site, or use host headers. Of the three methods, it is morecommon to use host headers than to assign unique IP addresses to Websites or to use non-standard TCP port numbers.

Note After you configure a host header or multiple host headers for an IPaddress, you must register the host headers with the appropriate nameresolution system. If your computer is on an intranet, register thehost header name or names with the intranet's name resolution system.If your computer is on the Internet, register the host header name ornames with the Domain Name System (DNS), which is administered byInterNic.
