I am trying to figure out how a client server program our company uses
The client part of the program communicates with the server via TCP/IP.
When a connection is established, I can see the server's IP address
listed at the top of the program's screen. Additonally, the client has
its own TCP/IP address.
BUT!!! During the client setup, I never have type in the IP of its
server. It seems that the client, in some unknown fashion, resolves the
server's IP address.
My question is how? What protocol could possible allow this? DNS comes
to mind for me. However, I know for a fact that this C/S program does
not use DNS. What could be facilitating the IP resolution of the server
for the client?
Any help on this would be GREATLY appreciated.
Additionally, do any of you know of a good free IP sniffer available for
