You seem to be saying, above, that IPv6 is also a real fix, presumably
because it allows for the 64-bit host id portion of an IP address to
"fast flux". Or have I misunderstood?

It would be nice for someone to explain how (or if) IPv6 changes this
situation since many networks are already well into the planning stages
for IPv6 deployment within the next two to three years.
