This will search your IAL for the active channel. This is useful if you recently kicked somebody and they join with a new name and same host.

Basically you know the address of the person you kicked so example:

You kicked Xi using hte host *@user.someisp.net.tt

Then they join as Dolphin, and start causing trouble (like flooding) (later on) and it would be too slow to whois and figureout if it was the same address so

/searchaddr

; /searchAddr (address)
; Searches for the address and returns all nicks using that address
; Good for when kicking somebody and they coming bakc under a false name
; /searchAddr *.staff.mugglenet.com
; 
; Usi

searchAddr { 
  var %a = $active
  if ($ialchan(*,%a,0)) { 
    var %i = $ifmatch
    while (%i) {
      var %address = $ialchan(*,%a,%i) 
      var %nick = $ialchan(*,%a,%i).nick
      var %host = $ialchan(*,%a,%i).host
      if ($1 iswm %host) { 
        echo -a %nick using ( $+ %host $+ ) 
      } 
      dec %i
    }
  }
  else { echo -a No addresses found } 
}
