Is there another way to find the subnet mask than:

String subnetMask="/"+networkInterface.getInterfaceAddresses().get(0).getNetworkPrefixLength();

Thanks!!!

JRE build 1.6.0_04-b12 had similar problem on Windows platform, it looks like heritage of that at the first glance, see http://stackoverflow.com/questions/6665808/getnetworkprefixlength-returns-strange-subnet-mask – Sasa7812 Oct 04 '13 at 09:03
