IP address, 192.168.168.168, and subnet mask, 255.255.255.0, which will work well
for most installations. In most cases, leave the default LAN IP address and subnet

the same subnet as the LAN IP address, or leave the default
range unchanged. The default DHCP range will work for most
installations.
