Comment 5 for bug 1801132

Andres, if you can still reproduce this, can you check the database to confirm if the duplicate is indeed a DISCOVERED IP address?

It's also possible (though less likely, I think) that it could be an IP address linked to multiple interfaces. This could be seen with a DISCOVERED address, but not really any other IP address type that I'm aware of. (Though since the model supports it, we might consider allowing IP addresses to be linked to, for example, both a bond and its parent. That could alleviate some of the strange behavior we sometimes see when creating a child interface, whereby the parents' IP addresses are removed. That would be a change too risky for this cycle though.)
