Parameters:

name -

Returns:

A valid IPv4 multicast address

getClusterableInterfaces

public static Iterator<NetworkInterface> getClusterableInterfaces()
                                                           throws SocketException

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

Returns:

An iterator of suitable NetworkInterfaces

Throws:

SocketException

addressFromIpString

public static InetAddress addressFromIpString(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:

IllegalArgumentException - if the string is not a valid IP string

isLoopbackInterface
