It would probably devolve into a debate of "legitimate." Maybe we could try the reverse: "IPv6 is a practical means to determine useful information." What useful information is expected? I'm trying to describe the best current practice. > DNS > timeouts already consume a large portion of MTA resources when > attempting to discover reverse DNS entries.
