Khaled, I understand that irony, sarcasm, and implicit statements can get lost in translation; as such, I wanted to reply once in no uncertain terms to avoid any confusion. Your proposal will not become a RFC. It uses a technique which was actively removed from the standard and even if that was not the case, it's way too late. We took ~20 years to get to the level of IPv6 adoption we have today. Any gains made during that time would be removed with any, even partial, technology reset. And this ignores the fact that IPv4 is almost at the end of its useful life and will largely be replaced; prolonging that process is not in the interest of the IETF nor of the networking community. While you are free to follow the process of writing and submitting an actual ID, believe me when I say that this will not become a RFC. Richard
