Problem Definition

Actual type of the Internet protocol (IPv4) has not considerably altered since it was presented in 1981. The IPv4 protocol verified robust, somewhat so straightforward for implementation and interoperable, which endowed its survival throughout a fast growth of the Internet through years. However, the exponential development of the Internet (whose proposition was unrealistic at the time when IPv4 emerged) adds new claims that IPv4 will not fulfil in an agreeable way. Some of the difficulties are the following: need of address space, fast enlargement of routing benches (causing decrement of the routing speed), require for a easier configuration, demand for a real-time facts and numbers move, and increased obligations contemplating security.

To eradicate some of the cited imperfections a new type of the Internet protocol (IPv6) was evolved in 1990s. Although the IPv6 protocol is still evolving, it is completely purposeful and its implementation and usage in genuine networks is possible. During the next couple of years the new IPv6 protocol should restore an vintage IPv4 protocol. Because of tremendous dimensions of the Internet, transition from IPv4 to IPv6 will not be instant. It will be a method that will last for a certain time span of time and proceed through distinct phases. Therefore, throughout the next years both IPv4 and IPv6 will coexist. The new IPv6 protocol inserts new characteristics, possibilities and improvements, particularly contemplating ease, routing pace, value of service and security. IPv6 adds new security means that are much advanced in evaluation to IPv4, but their evasion and abuse is still likely . Considering security, particularly awkward is the transition time span throughout which both IPv4 and IPv6 coexist. During the transition time span network security can be influenced by both security matters exact for IPv4 and IPv6 networks. Besides, distinct transition means convey new, before unidentified, security matters that can possibly supply new possibilities of intrusion and abuse of computer schemes attached to the network.

Since the transition time span will not be short, these security risks due to transition means should be gravely taken into consideration. Generally, the IPv6 protocol is more resistant to some security risks than the IPv4 protocol, but there are some security risks contrary to IPv4 networks that might furthermore sway an IPv6 network. Also, some new security risks exact to IPv6 networks emerged. Different security means utilised in computer networks, for example firewalls and intrusion detection schemes, should be cognizant of these new threats. Therefore, firewalls and intrusion detection schemes require to be upgraded to support and identify the IPv6 protocol correctly.

 

Aim

IPv6 protocol, which should restore the genuine IPv4 protocol, adds numerous new possibilities and improvements contemplating ease, routing speed, quality of service and security. In evaluation to IPv4, IPv6 improves means for guaranteeing a secure and secret move of information. Despite these improvements, network security continues a very significant topic since ...
