@tommyk sorry. Dang if I know. Maybe just examples of how it could be.
127.0.0.1 is the address for localhost , in ipv4
::1 is the same loopback address in ipv6
::ffff:127.0.0.1 is an IPv4-mapped IPv6 address that represents the standard IPv4 loopback address (127.0.0.1) inside an IPv6 networking format
192.168. Is a typical default network address setup
I leave it empty, cause I don’t want to force my devices to fixed addresses (dont want the mgmt job)
