I'm trying to automate our net abuse report and am having a tough time extracting a list of IP addresses from a file. All I want to do is go though the file and build a list of every IP address contained within.

The $1, $2 business is turning out to be a bit confusing.
Can anyone help me out with a code example?
Thanks a lot!
