Hi, Lee

This is what I have came up with using a similar approach, but as a raw 
regexp. You must adapt and escape to gambas language.

((?:[0-9]{1,3}\.){3}[0-9]{1,3})

The external parenthesis makes the group that captures all matches. 
Don't forget to apply the "/gmi" modifiers, which stands for "global", 
"multiline" and case "insensitive", if needed. See it working in my example:

All matches should be accessible as an array, if I am not mistaken.

Please, test it and report back if it worked for you.

On the other hand, there are other ways to write the regexp to be more 
accurate and look for an actual (valid) IPv4, for example:

(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$

But I don't think it's worth it for your needs.
