Set the unicastAddress to be used by createServer(DOF) . This is a convenience so that you don't have to keep the address around until createServer is called. The default is null, so if this method is not called, createServer(DOF) will throw IllegalArgumentException.

This method signature is only useful if you plan on calling it much later than the constructor and don't want to pass around the ucastAddress parameter you will need to call createServer(DOF, DOFAddress) . If that is not your use case, then just call creates(DOF, DOFAddress).
