For each packet sent out, there is an acknowledgement sent back. Fail to react to the handshaking protocol and the connection is terminated. TCP/IP does not differ from other protocols in that aspect. You might be able to setup a server that uses forged sub net addresses, but the server itself must have a valid address, otherwise it would not be able to communicate with other servers.
