Description

SubnetUtils does not handle /31 and /32 CIDRs well.

This should be documented and/or fixed.

192.168.0.1/32 causes an IllegalArgumentException to be thrown (by the way, that should show the upper and lower bounds)

192.168.0.3/31 gives
addressCount=0,
low =192.168.0.3
high=192.168.0.2
and 192.168.0.3 is rejected as not in range
