That won't help. It will add perhaps 25% to the lifetime of the
address space, no more.
64 bits of address space would have been fine to give
everyone all the addresses they would need. 128 bits gives
them all the networks they will need.
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.
