No.  As IPv6 takes off there will be less and less need for most
of us to have IPv4 addresses at all.  Eventually lots of IPv4
assignments should be returned.

Who of us worries about our email domain having a A or AAAA record
anymore?  There was a time when you would have both a A and MX
record at the domain.  These days just a MX will do.

Similarly the need for IPv4 addreses will go away.  IPv4 addresses
will be used by private networks.
