This address is the address of the multicast group. That is the group of
all computers that wants to take part in this communication. The IGMP
protocol maps this address to the IP addresses of all those participate
in
the multicasting.
For more information and a good introduction  on multicast 
communication
with Java goto
http://java.sun.com/docs/books/tutorial/networking/datagrams/broadcasting.html

Also read the book "Using the Java 2 Platform" by Joseph weber if
possible. It contains more details on multicasting and how to do it in
java explained in a simple way.
