Victor Romero commented on NET-523:
-----------------------------------

The method SubnetUtils::setInclusiveHostCount(boolean) does not fix this problem.

>             Project: Commons Net
>          Issue Type: Bug
>    Affects Versions: 2.0

> The following code:
> SubnetUtils subnetUtils = new SubnetUtils("192.168.0.1/32");
> throws the following exception:
> Exception in thread "main" java.lang.IllegalArgumentException: Value [32] not in range (-1,31]
> 	at org.apache.commons.net.util.SubnetUtils.rangeCheck(SubnetUtils.java:216)
> 	at org.apache.commons.net.util.SubnetUtils.calculate(SubnetUtils.java:141)
> 	at org.apache.commons.net.util.SubnetUtils.<init>(SubnetUtils.java:46)
> 	at com.gs.configmgt.proteus.model.impl.TestTest.main(TestTest.java:12)
> /32 is a perfectly valid subnet of one host. See wikipedia for verification: http://en.wikipedia.org/wiki/IPv4_subnetting_reference.
