This is used to limit the bound interfaces and ports that Hazelcast associates with.
<network>
<port auto-increment="false">5701</port>
<interfaces enabled="true">
<interface>192.168.0.*</interface>
</interfaces>
</network>
NetworkConfig nc = config.getNetworkConfig();
nc.setPort(5701).setPortAutoIncrement(false);
nc.getInterfaces().addInterface("192.168.0.*");
