It says: This document attempts to borrow the best from all of the existing IPng proposals (CATNIP, SIPP, TUBA). which is, as all the real engineers know, the surest way to lose, though politicians think it the best compromise. It should also be noted that SIPP is already a union of SIP and PIP, though Paul Francis, who proposed PIP, was, in the face of SIPP, saying "PIP is dead". So, SIPP was developed highly politically, though its address is still 64bit long. Masataka Ohta
