So the address space for IPv8 will be... </troll>
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.
And (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.

I suggest that the DNS name space should be considered to be an "hierarchical host address space" thus satisfying (1) and making (2) moot.
