I have mistakenly been tracking an asset group for my workstations based on IP. I now notice that I have multiple entries for the same host because the network is DHCP and the IP's are periodically changing. I want to clean this up and start tracking based on DNS or Netbios. What would happen if I start tracking a host based on DNS or Netbios? My point of confusion is in this scenario there are multiple hosts with the same DNS name but different IP's. Will these be combined or will that host be tracked based on DNS from that point on and the old entries will remain?
