Currently that detail is not retained in the DB.
Using IP Address would as part of inventory would be the closest simple thing to do.

I believe there has been talk about retaining it, but I don't recall any specifics about when that may be.

Here is one idea to vote for along those lines...

It is about having that detail on the Device Summary Page in the ZCC, but having it here would require it to be in the DB, which would make it available for inventory.
