I read about join relationship. I tried the following: Connect Host to IP using the IT World Links Contained Relationship to display each host with its IPs. Then I want to add the join relationship which should narrow the results to display only the IPs that their IP DNS Nams is not equal to the Host Display Label, however it seems that the join relation works on all the IPs and not only the IPs that are contained in the host. I don't know how to achieve both conditions. Can you help ?
