I have a few alerts created by DFM regarding duplicate ip addresses. It happens that those duplicate ips are in reality virtual ip addresses configured on our load balancers.
This is a known issue (CSCee02681). The only workaround is to unmanage those IP addresses that are being reported as duplicates. This can be done under DFM > Device Management > Device Details. Expand the details tree, and select the IPs that are showing up as duplicates and set their management states to false.
