I'm not seeing any outbound IPv6 traffic from my CentOS 7 box on the WAN

So ... Alice if you want to configure the system with the older EUI64
behaviour then in your ifcfg file for that interface you need
IPV6_ADDR_GEN_MODE=eui64 and then restart NetworkManager (or `nmcli
conn reload` rather than a full service restart or `nmcli conn mod

nmcli: unwanted secondary ip-address
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:

After upgrade to CentOS 8.1 default gateway missing
Hi,
Tonight I upgraded two CentOS 8 boxes to CentOS 8.1 (1911). Then after a
reboot of the first server the network was unavailable. In IPMI console
everything except the network was looking good. Network was unreachable.
No errors in NetworkManager. I also restarted NetworkManager, but it did
not help. Then I discovered that the default gateway suddenly was missing.
Then I rebooted the
