who<p>Which <a href="https://social.tchncs.de/tags/HTTP" class="mention hashtag" rel="tag">#<span>HTTP</span></a> status code do you expect, if you connect to a <a href="https://social.tchncs.de/tags/IPv6" class="mention hashtag" rel="tag">#<span>IPv6</span></a> only Webserver via <a href="https://social.tchncs.de/tags/IPv4" class="mention hashtag" rel="tag">#<span>IPv4</span></a>.</p><p>Talking about the situation, where the Website only has an <a href="https://social.tchncs.de/tags/AAAA" class="mention hashtag" rel="tag">#<span>AAAA</span></a> record, but the Webserver is also addressable via IPv4 (for other Websites).
