Rory Winston closed NET-305.
----------------------------
Resolution: Fixed
Fix Version/s: 2.1
God spot, thanks. I've added a method
SubnetUtils::setInclusiveHostCount(boolean)
which will make SubnetUtils work exactly as shown in the Wikipedia table. I've
also added all of the cases in that Wikipedia page to a test case.
Thanks!
