Configuring scan ranges

GFI LANguard N.S.S. enables you to configure ranges and exclusions to scan ranges for IP addresses to scan. These are set up in the ‘computer or range’ field within the new scan wizard.

Scan ranges

Ranges are configured through the use of the ‘/’ character. Through this character users can, for example, key in:

•	192.168.0.1/165

This will scan all the available addresses from 192.168.0.1 to 192.168.0.165.

Scan range exclusions

Scan range exclusions are configured through the use of the ‘+’ and ‘-‘ characters. Ex:

•	+192.168.0.1/165

•	-192.168.0.13

In the example above all the available computers which IP address is in the 192.168.0.1 to 192.168.0.165 range will be scanned, except for 192.168.0.13. which will be excluded.
