If a MID Server is configured with the default Include range name=ALL, with range=0.0.0.0, then any excluded ranges on that MID Server are ignored.
Steps to Reproduce
Select an IP device to discover (for example, 220.127.116.11).
Go to an instance configured to use only one MID Server.
Configure IP ranges on this MID Server to have the following two ranges: an Include range for all (name = ALL, range = 0.0.0.0) and an Exclude range = 18.104.22.168.
Create a Discovery schedule for 22.214.171.124 using Mid Server selection method = Auto-Select Mid Server.
Run the Discovery.
Instead of using ALL, use the following IP Range: 0.0.0.0-255.255.255.255
