No, it does not. It's only twice as much as 64 bits, and 64 bits is only twice as much as 32. Addressing schemes consistently allocate addresses in a terribly shortsighted way as bit spans, rather than address ranges, so address ranges are consumed much more quickly than they should be. This seems to be one of the most consistent mistakes of computer engineers ever since computers were invented. After all these decades, they still have no clue. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
