I have my server running CentOS and initially installed with the minimal installation. The IP address on install was 192.168.1.100 however after a few months I wanted to mess around with the GNOME GUI and installed it paying no attention to the network setup portion thinking it wouldn't have any affect but I was wrong. When the gnome shell was installed my server's IP changed to 192.168.1.155 and I had to make adjustments accordingly. Now everytime the internet kicks out and comes back on it switches between the two for no reason. I have to go into the server and show the "ip addr" to confirm the running IP address and it's driving me insane.
Anyone know what this is about and how to stop the changes?
