Well, without any concept how to fill 16 octets with routable information such that all users can be mobile while being involved in unicast or 
anycast or multicast.


"However, if we were going to extend IPv4 with more
bits, here's one strategy:"

I also thought about the option field, though not as fine-tuned as you did. And: that the leading octets might be placed 
there and eventually moved from there to some other place like to a locator and vice versa. First of all however  that  in the abstraction we have to
extend ipv4  with leading octets.

Hi Heiner,

I think the day for this has past. For better or for worse IPv6 is
slowly happening. However, if we were going to extend IPv4 with more
bits, here's one strategy:
