in a nutshell we were monitoring all our network devices using a polling ip of 10.10.10.xx. We created a new VLan and added ip addresses 10.10.220.xx to all the switches, we then removed the old ips. I manually changed the polling IP address in NPM to the new one. Now the old ip is still showing under all ip addresses for each device, and when I hit edit node it gives me the option to select ip address and shows the old and new one.
what is the trick to remove these old ip addresses?
Thank you
