    Description

      I think that xx.yy.zz.aa/0 should be accepted value by SubnetUtils, where xx.yy.zz.aa is any valid IPv4 IP address.

      Test case:
      SubnetUtils subnetUtils = new SubnetUtils("10.10.10.10/0");

      However it throws exception:

      java.lang.IllegalArgumentException: Value [0] not in range (0,32]
      org.apache.commons.net.util.SubnetUtils.rangeCheck(SubnetUtils.java:304)
      org.apache.commons.net.util.SubnetUtils.calculate(SubnetUtils.java:229)
      org.apache.commons.net.util.SubnetUtils.<init>(SubnetUtils.java:52)

      (I have updated issue description from original, to reflect that issue is not only with 0.0.0.0/0)
