<div class="para-description">
Your Internet provider (ISP) should support IPv6. If you haven't, you should first contact your ISP and ask them for IPv6 addresses.<br/>
If your ISP does not support IPv6, you can use an IPv6 tunnel to get IPv6 connectivity.

If you want your website to be only available by IPv6, you can do the following:
<ul>
<li>Create an AAAA DNS entry that points to the IPv6 address of your website.</li>
<li>Create an A DNS entry that points to 185.203.114.115 (that is this site).</li>
<li>From now on visitors that use IPv4 and try to reach your site will be shown this page.</li>

<li>Replace YOUR_URL with the URL that you want the user to come back to, when they have IPv6 enabled</li>
