Hi Khaled,

How should one create running code out of a flawed specification?
The following picture from your draft already shows that
it definitely cannot work, thus no code needed:
an IPv4-_only_ host by definition does NOT support IPv10
and thus CANNOT send any IPv10 tunnel packets. Same for an
IPv6-_only_ host.

IPv10 Host                                         IPv10 Host
    PC-1                                                PC-2
   +----+                                              +----+

   +----+                                              +----+
  /    /   <--------------------------------------->  /    /
 +----+              IPv10 Header (Tunnel)           +----+
                              (3)
IPv4-Only Host                                    IPv6-Only Host

Do you see the contradiction here?
