One final note: it seems that problem may be overcame by removing contents of /run/network just before reboot/shutdown.

There are two networks each: $ ip -4 addr show dev eth0 2: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 inet 10.1.1.51/24 brd 10.1.1.255 scope global eth0 inet 10.2.1.51/24 brd 10.2.1.255 scope global eth0 $ ip -6 addr show dev eth0 2: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 xxxx:yyyy:zzzz:201::33/64 scope global valid_lft forever preferred_lft forever inet6 xxxx:yyyy:zzzz:101::33/64 scope global valid_lft forever preferred_lft forever inet6 fe80::aaaa:aaff:febb:ccdd/64 scope link valid_lft forever preferred_lft forever (Global addresses and MAC address anonymized) Both are configured within "manual" entries in /etc/network/interfaces. When I turn down eth0 and bring it up again, the result is: $ ip -4 addr show dev eth0 2: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 inet 10.1.1.51/24 brd 10.1.1.255 scope global eth0 inet 10.2.1.51/24 brd 10.2.1.255 scope global eth0 $ ip -6 addr show dev eth0 2: eth0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 fe80::aaaa:aaff:febb:ccdd/64 scope link valid_lft forever preferred_lft forever That is, the global IPv6 addresses are lost.
