------------------------------------
Summary: SubnetInfo#toCidrNotation - allow a subnet mask
Key: NET-624
URL: https://issues.apache.org/jira/browse/NET-624
Project: Commons Net
Issue Type: Bug
Affects Versions: 2.0
Reporter: Makoto Sakaguchi
An IPv4 subnet mask, which is also the network mask, must consist of a set of
contiguous 1-bits followed by a block of 0-bits (i.e. 255.255.255.0), but it
does not check.
{code}
/* 255.255.0.1 is 11111111.11111111.00000000.00000001 in binary */
SubnetUtils su = new Subnet("192.168.0.1", "255.255.0.1"); // expect error
SubnetInfo si = su.getInfo();
System.out.println(si.getNetmask()); // Expect error or 255.255.0.1
255.255.128.0
{code}
