This overstates the case, or at least shows confusion over what we meant by the term "enterprise" in RFC-1918. I don't know about the other authors, but I meant an enterprise that was an end user, and specifically *not* a service provider. Nevertheless, SPs *are* using the space today. That is the world in which we live, no matter what 1918 says. What, then, is the best approach to deal with the conflict (if it exists– see Rob Elz's note)?
