We could discuss IPv8 and IPv16...
The question I would ask about your model is how one determines whether =
one is looking at a 32 or 64 bit destination address. Does one, for =
example, have to parse the options field before making that =
determination? How does that work in a router that drops an IPv4 header =
that is not 20 bytes in length?
There were a number of options kicked around that, in one way or =
another, reused packet fields (what is we assume that fragmentation =
doesn't ever happen?) or inserted options. Right, wrong, or indifferent, =
it wasn't that it wasn't considered, it was that it wasn't chosen.
