VPNs have emerged as the key technology for achieving security over the Internet. While a VPN is an inherently simple concept, early VPN solutions were geared towards large organizations and their implementation required extensive technical expertise. As a consequence, small and medium-sized businesses were left out of the e-revolution. Recently, VPN solutions have become available that focus specifically on the needs of small and medium-sized businesses. Historically, the term VPN has also been used in contexts other than the Inter ....etc

Based on internet technology, intranets are becoming an essential part of corporate information systems today. However, internets were not originally designed with businesses in mind. It lacks the technology required for secure business transactions and communications. A challenge therefore arises for businesses with intranet, i.e. how to establish and maintain trust in an environment which was originally designed for open access to information. More specifically, a way has to be found to secure an intranet without impinging on its ....etc

Growth of the Internet raised issues that were not envisaged during design of its underlying protocol. Internet Protocol version 4 is faced with the twin problems of lack of scalability and flexibility. Efforts are ongoing in the design of next generation Internet Protocol (Ipv6) that overcomes these drawbacks and provides future safe extensions. The base protocol and various supporting protocols have been standardized.
Additionally various issues are being worked on and of experimental nature. We have studied and implement ....etc

IP Addresses:Classful Addressing
RULE:
If a protocol uses N bits to define an address, the address space is 2N because each bit can have two different values (0 and 1)and N bits can have 2N values
Network Addresses
The network address is the first address
The network address defines the network to the rest of the Internet
Given the network address, we can find the class of the address, the block, and the range of the addresses in the block
In classful addressing, the network address (the first address i ....etc
