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

This method is only useful if you plan on calling createConnection much later and don't want to pass around the ucastAddress and mcastAddress parameters you will need to call createConnection. If that is not your use case, then just call createPeerConnection(DOF, DOFAddress, DOFAddress) .
