The Internet Protocol (IP) defines the format of information transported over the Internet. Data to be sent is divided into individual and completely independent packets. The Internet Protocol also specifies how the packets are addressed for delivery. Each computer (or host) on the Internet has at least one IP address that uniquely identifies it from all others, and each data packet contains both the sender's address and the receiver's address.
DCOM communication typically uses TCP/IP to transfer information between the different modules.
