True although a library or application using the Socket or SocketChannel 
APIs can cycle through the addresses too. I think there is general 
agreement here that having some support for this in the Java platform 
would be useful but I think it will require exploration and prototypes 
in order to see what new APIs and specification changes will be required 
to support it.
