Please do not be offended, but if you do not already know the answers to such questions or at least better places than the main IETF mailing list to ask them, then it is practically certain that you would be better served to use UDP/IP instead of raw IP. The number of available IP protocol numbers is infinitesimal compared to the number of UDP port numbers. (The host addresses can be seen as qualifying port numbers, but protocol numbers are global.) That implies that as long as the IANA is doing its job, it will be quite difficult to get an IP protocol number. Vernon Schryver vjs@rhyolite.com
