Using 'cut' is kind of vulnerable to formatting changes, though. I'd
use something like this Perl code:
if (/\sinet addr:([0-9.]+(\s.*\smask:([0-9.]+)/i) {
$ip_addr = $1;
$ip_addr = $2;
}
That recognizes the values based on how they're labeled, which is likely
to be much more stable between versions.
