2 ips 1 nic, cannot remove permanently and where from originate?
Hello.
Ubuntu 16.04
Having issues with 2 ip addresses showing up on 1 nic which I know is not that unusual, except that 1) why would my system create 2 ip addresses on 1 nic (I certainly never created it) and 2) how can I permanently stop that from appearing after every reboot?
Of importance is to get to the bottom of *why* and from *where* this additional IP addresses is coming from.
After boot:
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
inet 192.168.1.236/24 brd 192.168.1.255 scope global dynamic enp2s0
valid_lft 86309sec preferred_lft 86309sec
inet 192.168.1.4/24 brd 192.168.1.255 scope global secondary enp2s0
valid_lft forever preferred_lft forever
after ip addr del 192.168.1.4/24 dev enp2s0
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether xx:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
inet 192.168.1.236/24 brd 192.168.1.255 scope global dynamic enp2s0
valid_lft 74429sec preferred_lft 74429sec
But this doesn't stick on reboot.
