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