Nice.

It's fun to try to come up with different solutions. I guess we
haven't mentioned this yet:

:r !printf '192.168.0.\%s\n' {1..254}

This one needs bash shell.

{1..254} is a feature that bash copied from ksh93 which it
itself copied from zsh. And in zsh, you can use print -l to
avoid having to use printf as I said in an earlier message:

:r! print -l 192.168.0.{1..254}

Personally, I find using ! neater that using vim's extension
language as it appeals to my taste for orthogonality

With zsh, you can also do:

:r! repeat 254 echo 192.168.0.$((++i))

POSIXly, you can also do:

:r! awk 'BEGIN{while (++i<=254) print "192.168.0." i}'
