HI As i know ,Java currently has no facility for accessing or determining a subnet mask. A subnet mask is used to denote which bits in an IP address are the "network" part and which bits are the "machine" part. I think you need to broad cast the message accorss defferent networks(or one Network). Possible solution might be get the All IP's in that network(s) and brodcast the message to all(Might be the soluation). Surya.MP
