Re: IPv4 Address Pool Has Been Expanded Significantly
Hi, Nanashi:
1) " By this expanded definition, EzIP is not backwards compatible, because it uses v4 unless both sides have EzIP. ":
Backward compatibility in this case means that the new system (EzIP) is able to transparently handle the old format (basic IPv4), so that no one is required to be capable of the advanced capability (EzIP) if not interested in it. Thus," falling back" to requiring both sides to use IPv4 when someone in the loop is not capable of EzIP is actually conforming to the Kosher definition of "backward" compatibility.
2) "Operators and users need to deal with both. ": Actually, the current "operators" (the CR & ER - Core and Edge Routers) are not expected to handle EzIP at all, because the Option Word is transparent to them. Only "users" are encouraged to upgrade their IoTs to be EzIP-capable, so that they can enjoy the straight routing that offers end-to-end connectivity.
