to make v6 work tarks end users more work than v4
if "v4" includes dealing with an increasingly severe shortage of
address space (which sooner or later implies forced renumbering)
and/or tying together multiple NATted networks, it's not at all
clear that this takes less work than v6.
It certainly takes more. The amount of NAT equipment out there is
astonishing, and as I said at the plenary, people are starting to pay
Real Money (as in millions a year) in large organizations to keep the
NATs working properly. Several layers of NAT has become common, and
NATs are stateful, which means they are necessarily more of a
reliability problem than routers.
v6 is really no harder to use than the old v4 pre-NAT network was.
It is true that v6 qua v6 does not solve the route explosion
problem. It is also true that the route explosion problem is a real
problem. However, it doesn't make it worse, either.
