Known client-List in "Client group management" should be sorted correctly

Current sort order is:

192.168.0.1
192.168.0.11
192.168.0.2
192.168.0.200
192.168.0.3

it should be:

192.168.0.1
192.168.0.2
192.168.0.3
192.168.0.11
192.168.0.200

The default sort order (when opening this page for the first time) is: Show in the order in which they were added.

I see that the sorting is also somewhat off when you click on the IP title row. I will check this. Thanks for your report.
