Description

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.
