I have reports I've set up that retrieve the Top 50 NetFlow Receivers for certain IP address ranges, and the report populates with the Byte count and IP addresses. Then I added a column to display the Full_Hostname, and some addresses are resolved to names while others aren't - they just show the IP address. All these addresses have names in the DNS and are resolvable from the NPM server. What needs to be done to get the correct name listed?
