Parameters:

name -

Returns:

A valid IPv4 multicast address

getClusterableInterfaces

public static java.util.Iterator<java.net.NetworkInterface> getClusterableInterfaces()
                                                                              throws java.net.SocketException

Find all network interfaces on the host that are suitable for clustering via multicast

Returns:

An iterator of suitable NetworkInterfaces

Throws:

java.net.SocketException

addressFromIpString

public static java.net.InetAddress addressFromIpString(java.lang.String ipString)

Takes a raw IP string and converts it to an InetAddress.

Parameters:

ipString - String representing and IP address

Returns:

InetAddress representing the same address.

Throws:

java.lang.IllegalArgumentException - if the string is not a valid IP string
