IP addresses (for instance, 192.168.1.10 to 192.169.1.50), a subnet or any IP
address? Select an option from the drop-down list box that includes: Single
Address, Range Address, Subnet Address and Any Address.
Enter the single IP address or the starting IP address in a range here.
Enter the ending IP address in a range here.
