NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.1.121
PREFIX=24
GATEWAY=192.168.1.1

DEFROUTE=yes

Answer 1

The ip has not changed, but there are additional ip addresses.

You can list all the ip addresses for the device using:

# ip addr list dev p4p1

which would show that there are multiple ip addresses for that device and that these change when launching/terminating instances in your cloud.

Answer 2

找到多个IP地址后，您可以使用以下命令删除一个-

ip addr del 169.254.169.254/32 dev p4p1
