title: Accessibility for servers with IPv6 and without IPv4
body: <p>I have a server that hosts many websites with Apache's vhosts function. Currently all sites have the same IP address as expected. I'm wondering if I can do something with IPv6 to give every website a unique IP address and stop IPv4 so that each website cant be seen as running on the same server.</p>
  
  <p>And how will the internet service provider handle requests to a website that does not have IPv4.</p>
