The problem is the really small size of the option type field in IPv6. There really only are 5 bits available for numbering both the hop by hop and the end to end options. That makes for a grand total of 32, of which three are assigned by basic IPv6 specs. So, there really are good reasons to be somewhat conservative with the assignments. -- Christian Huitema _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
