simple skcipt with "in", help please

RouterOS Scripting
1

Hellou,
i have very simple script:
return true/false if IP adress from registration-table is member any of range from array

:local Ranges [:toarray "192.168.1.0/24,192.168.2.0/24"]; \
:foreach i in=[/interface wireless registration-table find] do={ \
  :local lastIP [/interface wireless registration-table get $i last-ip]; \
  :foreach j in=$Ranges do={ \    
    :log info ( $lastIP ." is in range ". $j ." ?"); \
    :log info ( $lastIP in $j); \
  }; \
};

I tryed

  1. lastIp with “/32”
  2. convert function :toip

and nothing, any ideas?

PS: sorry for my english
