Would you mind elaborating what you mean by semantics in the statement
above?  Clearly there are semantics in things like the IPv4 multicast and
experimental address ranges (aka "Class D" and "Class E"); especially for
the multicast case, the very fundamental semantics of the distribution are
signalled using the address and there has been significant deployment using
those semantics.  Isn't that semantics in the meaning above?

Thanks for any clarification,

Ted
