Forums Scripts & Popups Change address into nick

I was wondering a very small thing.
We all know that you can use $address($nick,2) to find someone's host when using kick/whois/whatever scripts (example: *!*@bla.com can be JohnnyEnglish39's host)

Is there a way to reverse this situation?
That when someone lists an address (example: !lookup *!*@bla.com) it returns a nick (example: JohnnyEnglish39)

I already found the answer.

$ial($2,1).nick

does the trick where $2 is the address entered.

Just as a note... the IAL needs to be updated prior to using it or it will not always work properly.
