In 100 years, when we start to run out of IPv6 addresses, possibly we
will have learned our lesson and done two things:
(1) Stopped mixing the Host identification and the Network
identification into the same bit field; instead every packet gets a
source network address, destination network address, AND an
additional tuple of Source host address, destination host
address; residing in completely separate address spaces, with no
"Netmasks", "Prefix lengths", or other comingling of network
addresses and host address spaces.
(2) The new protocol will use variable-length address for the Host
portion, such as used in the addresses of CLNP, with a convention of
a specified length, instead of a hardwired specific limit that comes
from using a permanently fixed-width field.
Need more bits? No protocol definition change required.
