The "Custom Network" settings allow you to configure the following elements:

number of bits set in the subnet mask, for example 192.168.50.1/24 ).
The buttons at the bottom right of the editor panel depend on whether you add a new
custom network or edit an existing subnet. For a newly configured custom network,
click "Create" to add the subnet to the list of available custom networks or "Cancel" to
discard your changes. To edit an existing custom network, click "Save" to store the
reconfigured subnet or "Reset" to discard your changes. You can click "Close" to shut
the editor panel as long as no changes have been made on it.
