&gt; How do you know if you don&#x27;t have IPv6 endpoints?<p>For my open source projects I do not care.  For the business side of things at any company I worked for the bulk of the revenue came from a handful of countries where invoicing was set up, the interface was translated to, everybody spoke English in support etc.  If I would ever have to grow a business into an area where there is no IPv4 connectivity or problematic one, there would be plenty of other issues before.<p>&gt; And those sites will continue to be small with that kind of thinking.<p>One has nothing to do with the other.  Sites grow because they grow their consumer base and that has pretty much nothing to do with IPv6 connectivity (at the moment).  The future is irrelevant in this discussion as the thread was about why few people care <i>currently</i>.<p>&gt; The user stats show that the time is now. What kind of signal are you waiting for?<p>Not the stats I am looking at, but I&#x27;m willing to be shown different statistics.  For all companies I worked for IPv6 has been not even a topic worth discussing so irrelevant was it for the the operations.
