hello,
Lets say that there is a client which can connect to a server via port 
4100.  Is there some way for the client to broadcast a message over the 
network saying, i am looking for a server on any ip address that 
responds properly to a packet sent to 4100?  This way the client can 
simply come up on the network without a priori knowledge of what the 
server's ip/name is.  (This would only apply to a network on one side of 
a router.)

i can see where one can simply send a packet to every ip address in the 
networks sub mask[for(;;)].  but i am wondering if there is another way 
that would generate less traffic/use less computer resources.  (as we 
have hundreds of laptops connecting to our network daily, and a mask of 
255.255.0.0, but really only usually use 10.1.1.x or 10.1.2.x so 
everything from 10.1.3.x-10.1.255.x usually would be wasted.  however, 
there are no where near 255^2 network jacks/wireless connections to our 
network)

thanks,
charlie
