I=E2=80=99m only going to say one more thing on this subject because =
this is essentially a side bar that has very little to do with the =
subject matter of the OP. =20
If we hadn=E2=80=99t run out of address space we=E2=80=99d still be =
trying to fix IPv4. The numbers don=E2=80=99t lie. It=E2=80=99s not =
very likely that we=E2=80=99re going to be space constrained on the IPv6 =
Internet like we are on the IPv4 internet. Nobody is going to want to =
repeat the pain of the last 17 years of trying to convince people to run =
IPv6.
Just about every technical challenge with the underlying protocol stack =
is fixable. Except for one: what happens when we run out addresses. =
For all of its flaws, IPv6 addresses this one particular issue quite =
well.
