Sebb commented on NET-641:
--------------------------
No.
If you look at the Javadoc for isInRange(String), which calls
isInRange(integer), you will see that 0.0.0.0 can never be in the range because
it always excludes the broadcast and network addresses.
Changing that would be a change to the published API.
> SubnetUtils.SubnetInfo.isInRange("0.0.0.0") returns true for CIDR/31, 32
