i was using a script to identify where someone was logging in according to their IP as shown below.

IF $IP1and2 = " 10. 12"
Select
Case $ip3 = " 55"
$LOC="Test Site, VA"
USE $Netlogon @Lserver + "\NETLOGON"

Well now i'm running out of IP ranges so i have to start subnetting. How do i write it if i want to identify 10.12.55.1-62 255.255.255.192?
