「ip -d addr」を実行すると、次のように表示されます。
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 promiscuity 0

inet6 xxxxw/64 scope link

ただし、実行すると、service --status-all次のように表示されます。
IP x.x.x.1 already exists on eth0
IP x.x.x.3 already exists on eth0
IP x.x.x.4 already exists on eth0
私はしなかったeth0、なぜ？
