+The lib-ip-tools script is only used under specific conditions:
 - During initial setup, with whitelist mode, and only if wan interfaces were set to 'all', and LAN subnets were not specified via command line args. geoip-shell then assumes that it is being configured on a host behind a router and firewall, uses this script to detect the LAN subnets and offers the user to add them to the whitelist, and to enable automatic detection of LAN subnets in the future.
