pin_ptr commented on NET-641:
-----------------------------
In my opinion, javadoc is wrong.
It does not cause confusion if number of IP addresses that returns true when
passed to isInRange() and number of IP addresses returned from
getAddressCount() is always the same.
(Javadoc says they are differ if isInclusiveHostCount is true)
> SubnetUtils.SubnetInfo.isInRange("0.0.0.0") returns true for CIDR/31, 32
