Welcome to the end of the IPv4 Internet. Unfortunately the site you tried reach is not reachable by IPv4. To access {{ domain|default:"this part of the Internet" }}, you need to enable IPv6 on your computer.
<div class="para-title">How to enable IPv6 ?</div>
<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.

<div class="para-description">
If you want your website to be only available by IPv6, you can do the following:
<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 (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>
<div class="para-title">How to make some content only accessible by IPv6?</div>
<div class="para-description">
<li>If parts of your website should only be reachable by IPv6, you can redirect the user to <a href="https://no-ipv4-here.ungleich.ch/?back_to=YOUR_URL">https://no-ipv4-here.ungleich.ch/?back_to=YOUR_URL</a></li>
<li>Replace YOUR_URL with the URL that you want the user to come back to, when they have IPv6 enabled</li>
<li>We suggest to use a HTTP 302 (temporary location changed) for this</li>
