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

                 Key: NET-262
                 URL: https://issues.apache.org/jira/browse/NET-262
             Project: Commons Net
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Sebb


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
