IP addresses are divided into three major classes (A, B, and C) and two less familiar ones (D and E). Each class uses a different portion of the IP address bits to identify the network. There is a need for classifying networks because there is a need to be able to create networks of different […]
Although most people think of IP as the transport protocol used by higher-level protocols, one of its more important functions is to provide the address space used by the TCP/IP suite. The difficulty of having to create a routing table that consists of hundreds of millions of actual hardware addresses, providing for no built-in organization […]
TCP/IP was built using a layered approach. You may have heard about the OSI (Open Systems Interconnect or Open Systems Interconnection) Reference model that is used mostly as a framework around which a discussion of network protocols can be discussed. Developed in 1984 by the International Organization for Standardization (ISO), this model defines a protocol […]
