Hi,
the subject says it ... I have an interface that is being configured with IPv4 and IPv6 addresses via dhcp. I need to assign an additional IPv6 address to the interface. This is all very easy with network-manager but that seems to be kinda deprecated and we're supposed to use the anachronistic /etc/network/interfaces file. The manual page isn't helpful for this at all. So I have auto enp7s0 allow-hotplug enp7s0 iface enp7s0 inet dhcp iface enp7s0 inet6 dhcp How do I additionally assign fd53::40/16?
