Tore,
Um, haven't you heard that we are out of IPv4 addresses? The point of IP=
v6 is to expand address space so that the Internet can keep growing. Maybe =
you don't want to grow with it, but most people do. Eventually IPv4 will be=
dropped and the Internet will be IPv6-only. Dual-stack is just a convenien=
t transition mechanism.
