IP network mask

[mkpaz]

Suppose, we have an adress string and ones need to get IPv4 netmask address in octet format.

IPAddress ipv4Address = new IPAddressString("1.2.3.4/24").toAddress();
System.out.println(ipv4Address.getNetwork().getNetworkMask(ipv4Address.getNetworkPrefixLength()));

This code does its work, but it literally requires to specify the network prefix twice. First in the address string and then as arg in getNetworkMask(). Would it be possible to add getNetworkMask() method to IPAddress or inherit prefix length from IPAddress in getNetwork() ?

Yes, that seems reasonable.

This has been added to versions 4.3.1 and 5.1.0, getNetworkMask and getHostMask. Also added toZeroNetwork as mentioned in issue #28.
