Answer 1

Following Yuriy's answer: To get the whole range of ip addresses, the Apache Java class SubnetUtils offers the following methods:

String[] addresses = utils.getInfo().getAllAddresses();

To download the jar containing the class go to: http://repo1.maven.org/maven2/commons-net/commons-net/3.0.1/commons-net-3.0.1.jar
