well i think what they r trying to say is u use asp or php or anything (other than AS) that can retrive an IP ...

so it can be like this ::

1) user load your flash (.swf) ....

2) your .swf call a page with asp or php or what so ever that can retrieve an IP.

3) make the retriver do an output to the page such as client_ip="112.111.11.11"

4) load the variable using AS .... then u have it ...
