What I had in mind would be:
If the first bit is a 0, the address is 64 bits.
If the first bit is a 1, the address is larger than 64 bits.
If the 65th bit is a 0, the address is 128 bits.
The 65th bit set to 1 is reserved for future meaning.
However, the space actually has to be reserved in the packet headers,
so you'd probably need something like that in the header.
If the first nybble is 0, we use 64-bit addresses
If the first nybble is 1, we use 128-bit addresses
If the first nybble is 2, it's reserved for future use
If the first nybble is 3, it's reserved for future use
