joel at ubuntu:~$ uname -a

joel at ubuntu:~$  sudo ifconfig eth0:0 240.0.0.1/24
SIOCSIFADDR: Invalid argument
SIOCSIFFLAGS: Cannot assign requested address
SIOCSIFNETMASK: Cannot assign requested address

now go test that on every exisitng ipv4 device on the planet that's not
getting an upgrade.

it doesn't extend the life of ipv4 usefully and it wouldn't have if we
started 10 years ago either.

the goal in stringing along ipv4 is to not hose your current or
potential customers rather than prevent still more obstacles to their
success.
