Usually when you have multiple network connections in shared mode, then
network manager automatically chooses different IP address ranges (like
you have shown below), 10.42.0.1/24, 10.42.1.0/24, etc.

However, you can control this range if you want to.  After selecting
'shared' mode in the connection settings, set the IP address to the
first IP address (say 10.42.6.1) in the desired range (10.42.6.1/24) and
set the subnet mask suitable for the range (say 24, can't be less than
24, I think).

This looks nasty.  If you are trying to delete a connection and are
unable to, then you can work around by manually deleting from command line.

Network Manager terminal interface:

$ nmtui

Or using command line interface. List connections:

$ nmcli connection

Delete connection:

$ nmcli connection delete "<connection name>"

Hope this helps.
