On the Network Overview screen (Tools-->Network), sorting does not work on the "IP address (hostname)" column. Sort works on all of the other columns, but not that one. I have tried all themes and it does not work in any of them.
Why not just provide the same functionality as was in v5, where it sorted by the first address? In my case, that was almost always the IPV4 address. Is it possible to make two columns, one for V4 addresses and another for V6 addresses and then make each sortable?
