Internet protocols In this context‚ there are three layers of protocols: * At the lower level (OSI layer 3) is IP (Internet Protocol)‚ which defines the datagrams or packets that carry blocks of data from one node to another. The vast majority of today’s Internet uses version four of the IP

Subnetting— Determine the classes – Classful vs Classless Class A: The first bit in the first octet must remain a 0. The remaining seven bits can be a 1‚ giving a maximum total of 127. The first octet‚ however‚ cannot be 0 (local identification‚ or “this network”) or 127 (loopback). Class A first octet range is 0 through 127‚ although the valid range is 1 through 126. Class B: The first bit in the first octet becomes a 1. The second bit‚ however‚ must remain a 0. The remaining six bits can be a 1

It is different to other Internet security systems which is being use all over the place‚ such as Secure Sockets Layer (SSL)‚ Transport Layer Security (TLS) and Secure Shell (SSH)‚ operate in the upper layers of the TCP/IP model. Therefore‚ IPsec will protects any application traffic that came across in network. To use IPsec‚ applications do not need to be specifically designed. IPsec uses the following protocols to allow it to perform various vital functions such as

Unit 10 – Assignment 10.1 Networking Basics: In a network‚ there are many complex communications devices which are involved in management. Each of these enables access and connectivity to the network. This includes hubs and switches‚ repeaters‚ routers‚ bridges‚ gateways & wireless devices. Some of these are closely related‚ for example‚ switches and bridges. A bridge is a fairly simple technology‚ which is not usually used anymore. It would separate different parts of a network‚ reducing the
