We're not sure, Jim - maybe if there was an actual protocol spec, we'd know.
You might start by doing an RFC793-style packet header diagram.  Oh, and while
you're laying out header fields, make sure you understand subtleties like why
the IPv6 headers have fixed-length fields on doubleword boundaries (hint -
router manufacturers like ASICs)

> Are you familiar with how IPv16 works ?

The techniques outlined in the (recently expired) internet-draft
draft-terrell-math-quant-new-para-redefi-bin-math-04.txt have proven to be
quite challenging to implement in functional silicon or software.  Therefore,
you will have to find alternate means to deal with the 'version' field in the
datagram header.

Will the list management please consider doing something with Jim's posting
privileges until such time as he exhibits either an ability to write a
coherent paragraph on a network-related without mentioning IPv8, or sufficient
understanding(*) of protocol design to explain the previous paragraph?

(*) it's not THAT challenging - most first graders have a sufficient grasp
of mathematics to understand the equivalent problem in decimal notation...
