There is no GUID in most devices, so if i have three ip numbers on one device, that resolve to three dns entries, then it will appear as three devices.
until O/S (linux, etc) and built-in firmware get the concept of a GUID for a device, it will be hard.
A few solutions :
Technical approach : Have a facility where an ip address can be banned/blocked. Have a system where duplicate devices can be selected and merged. This means when you click on any three (in the above example) hostnames, you always get the same device record. This would need to show all three (in the above example) hostnames so people know what is happening.
Management approach : on the obs server, edit hosts file for one of the duplicate hostname/ip address and set it to something stupid that will never ping (for me on my network, 192.168.1/24 would work cause i'm on a 10/8 network).
