Right, but that's a mixed network.  The problem is when you have an IPv4
machine on an IPv6 network (or a mixed network) trying to access a remote
server that only supports IPv6.  Which is the case for a lot of Chinese
websites, for instance (and it's why a lot of Chinese companies that are
trying to sell to the west purchase hosting services in Europe or the US
since it's easier than trying to get IPv4 service in China).
