Short of running through every possble IP on the network attempting to make
actual connections, what you ask for is typically done using UDP.  You would
have the server open a UDP server socket on a given port.  The client can
then do a UDP subnet broadcast using that port.  Any server that receives
and processes the packet can decide if it can accept TCP connections on the
other port (4100, in this case) and send a response UDP packet back to the
client letting it know that the server is there and ready.
