That's checking whether $rdns, as a pattern, does not match the string
in $result.
That's why it "fails": It does not mean what you think it means.
It means, use $rdns as a pattern, to try to match the string in
$result. Then it returns false if the match succeeded or true if the
match failed (just the boolean opposite of what =~ would have done).
Here's another way to write it:
if (not ($result =~ /$rdns/ix) ) {
But you originally said "I want to make sure $result is NOT part of
$rdns." That's not the same as making sure that $rdns is not part of
$result.
Does this clear things up?
Cheers!
