Hosting more than one website on private machine
<p>I currently have two websites on my computer one is at the default port another is let's say at port 100 so if the IP address or my computer is 1.2.3.4 then
<a href="http://1.2.3.4" rel="nofollow">http://1.2.3.4</a> points to one site and <a href="http://1.2.3.4:100" rel="nofollow">http://1.2.3.4:100</a> points to another.</p>

<p>It works but I do not want to give the user the IP address at it might change.</p>

<p>I also have two domain names registered with some provider who allows me to modify "A" record of the domains. </p>

<p>However I could not figure out how to manage both sites at the same time. i.e how to ensure that siteone.com points at 1.2.3.4 and sitetwo.com points to 1.2.3.4:100  ? Is it possible at all ?  The "A" record seems to work only with the default port 80.</p>

<p>My HTTP server is Windows IIS.</p>
