hi Roue .. the part that shows what is displayed ip wise is this ..

on !1:JOIN:#: { window -De @joins
var %mask = $mask($fulladdress,2)
var %nfname = $mask($fulladdress,0)

what you would need to do is edit all where the $fulladdress,2 are and $fulladdress($1,2) bits only .. NOT the $fulladdress,0 ones. the 2 returns "what" is shown on the ip.
have a play using 1 , 2 and 3 till you find which you want .. eg $fulladdress,3
