OwenOwen, We have had this conversation before, but I just wanted to put my two cents out there again. I dont view /3 as a safety valve. I view it as a possible escape pod from a sinking ship. If it needs to be utilized, the entire world has been dealt a large disservice - something great pains should be taken to avoid. I doubt it would be an "oops, ime sorry, no harm done". It should not be a factor to add risk into allocation design. Furthermore, any allocation holder trying the same trick of reserving a greater than half of their block for the safety valve in their numbering scheme might quickly discover that their block is a bit more cramped than they thought it would be. For me, the entire debate boils down to this question. What should the objective be, decades or centuries? Joe
Decades... I think that a combination of other factors will likely conspire within decades to render the current IPv6 protocol obsolete and drive adoption of a replacement protocol. I don't know what those factors are, but, historically, few things in technology have stood the test of decades. Almost nothing has stood the test of centuries. Owen
