Putinas Piliponis commented on NET-529:
---------------------------------------
Patch in 3.4 (NET-511) is also not correct - IllegalArgumentException is thrown
with valid input:
+ if (cidrPart == 0 && address != 0) {
+ throw new IllegalArgumentException("Cannot have /0 cidr with
non-zero address");
+ }
> SubnetUtils throws exception on valid input

> Key: NET-529
> URL: https://issues.apache.org/jira/browse/NET-529
> Project: Commons Net
> Issue Type: Bug
> Affects Versions: 3.3
> Reporter: Putinas Piliponis
> Labels: SubnetUtils
>
> 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)
