Scanner Appliance Tour
Configure Static IP Address
31
Confirm the configuration
When you see SCANNER APPLIANCE NAME–IP ADDRESS this means you are ready to start
scanning. This message appears if the Scanner Appliance made a successful connection to
the Qualys Cloud Platform using the new configuration.
An appliance configuration error appears if the Scanner Appliance failed to make a
connection to the Qualys Cloud Platform. A error may occur because the static IP
parameters you entered are incorrect, or they do not match the static IP configuration on
your network. See
Troubleshooting for help with resolving the issue.
Tell me about LAN Netmask
When entering static network parameters, you will notice that the cursor does not appear
after the
LAN NETMASK
prompt and you cannot enter characters in the entry field. At first,
the netmask “255.255.255.000” appears. Use the Up and Down arrows to scroll through
valid netmasks. When the appropriate netmask value appears, press ENTER to confirm.
Possible netmask values are listed below. If you press the Down arrow, the values appear
in this order: “255.255.255.000”, “255.255.254.000”, “255.255.252.000... If you press the
Up arrow, the values appear in this order: “255.255.255.000”, “255.255.255.128”,
“255.255.255.192”...
