Forums Scripts & Popups ON DNS problem!

Can somebody help me with this little scripts:
How do i write a scripts to perform /dns a range of IP like:
/dns 203.162.123.1 to 254 and the return message like this:
*** Looking up 192.168.0.1
-
*** Resolved 203.162.123.20 to PassionNet
When the return message is PassionNet, it will perform a command like: /run c:\windows\ping 203.162.123.20
If the return message is not PassionNet, it will continue with /dns the next Ip in the list.
when it reach 203.162.123.254 it will return to 203.162.123.1
