You told it that it can use 20-254 and that's what it's doing.

The assumption is that the network administrator will configure it properly :-)

Seriously, it's impossible to test for all possible combinations of 
misconfiguration (this being but one). As you've discovered, with 
great power and flexibility comes a responsibility to configure it 
correctly - there should be no overlap between fixed addresses and 
dynamic ranges.
