I need to develop an IT Asset Tracking system for my work. It will include all printers, computers, external devices, etc.

I could develop one from scrach, but I am having problems defining the relationship between Asset -> Mac Address -> IP address (not all assests will have Mac address, and an asset can have many mac addresses) :rolleyes: . Therefore I want to see if somebody has already developed something so I can use it or use it as a reference.
