That's not necessary. For any setting that can be multi-valued (such as

thing ?
You first remove all ipv4.addresses and then add the one you want. Then you
save/activate.

Dear Mark,
thanks for the additional hints.

I'd just suspect some rogue dhclient running on the system.
Check the process list for dhclient instances and their cmdlines.
NetworkManager should not be running any dhclient for that interface
with this config.

That's really interesting. Doesn't NetworkManager also store other
Dear Simon,
every second IP-address is unwanted. We restarted eno4:
nmcli con down eno4; nmcli con up eno4
and the second address vanishes. Then after a few ours, the second ip
address reappears.
This is the config-file of eno2:
# cat ifcfg-eno2
TYPE=Ethernet
PROXY_METHOD=none

Okay, nothing to find here.
What about eno2, you also have two IP addresses there and even in the same
subnet, is this wanted or not? Can the second address of eno2 be found in
the ifcfg
Dear Simon,
And can you diff the config of eno1 and eno4.
# pwd
/etc/sysconfig/network-scripts
# diff -u ifcfg-eno1 ifcfg-eno4

Hi,
Can you show as the config of eno4?
And can you diff the config of eno1 and eno4. Looks like there is a
difference
Dear CentOS-Community,
we are facing the following issue:
A secondary ip address seems to be automatically added to a nic which
causes several issues in our setup.
This server is equipped with four nics which are currently in use:
