You can scan a class B network starting at a class C address? just type for example "192.168.100" for the address, and select "Class B" and the Network Scanner will scan from 192.168.100.1 to 192.168.255.254.
If you scan the local host address (127.0.0.1), the scanner will scan your local PC much faster.
