Tell HN: IPv6-only still pretty much unusable
We use it in production.  Much of our traffic comes in to us on it.<p>We dual stack, though, as we know we won’t be able to access all external resources we need over it.<p>If you are expecting everything else to work over v6 before you deploy it then you’re hoping to be the last network on earth to do so.  And there can only be one of them so that game of chicken can’t end.<p>There will be a very long tail of networks only on v4. Yep.
