  - <p>So let me get this straight:</p><p>- You need to enclose <a href="https://social.coop/tags/IPv6" class="mention hashtag" rel="tag nofollow noreferrer noopener" target="_blank">#<span>IPv6</span></a> addresses in square brackets when using them in URLs, because...<br>- The colon is already used to separate addresses from ports in URLs, and IPv6 uses colons to separate hex groups.</p><p>So the question is... why did IPv6 choose to separate parts with colons?! IPv4 used periods for that and I can't see why they wouldn't have worked for IPv6 too. Did they somehow go out of fashion? :)</p>
