What is needed is a way to signal to the server operators that the request could have been made over IPv6 so they can measure what percentage of their clients are theoretically capable of connecting to them over IPv6.  A HTTP header with a value of “yes” that is added to the request by the client if they have a global IPv6 address (includes ULA) and “no” if they don’t.
