In the previous section I presented an overview of current adoption of IPv6, described its main features, and detailed the new address protocol header format.

The Internet Protocol (IP) has some vulnerability that can be exploited to transfer information along the network by being anonymous. Some attempts have been made using IPv4 but now since IPv6 is the new mode of network the challenge is to design it to fit the new trend.

IPv6 uses NDP (Neighbor Discovery Protocol) to find the MAC address. NDP manages interaction between nodes via message exchanges. These messages provide the data necessary for the processes of host auto configuration and packet transmission on a local link. Host auto configuration involves separate tasks of Parameter discovery, address auto configuration and duplicate address detection. Packet discovery is facilitated through router discovery process. It obtains the necessary parameters required for host configuration. Duplicate address detection is used to detect the presence of duplicate addresses on the same link. Packet transmission process requires data which can be obtained by router discovery, prefix discovery, address resolution, neighbor

The TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.

The Internet Protocol (IP) is the most broadly utilized protocol as a part of web communications because of its consistent communication technology . such a variety of individuals are relying upon the protocol, because of the security examinations the IP got numerous patches and modification as it has been sent comprehensively.

The internet is everywhere. It has become the most widely used and accessed technology platform on the planet. It seems like it’s almost gotten to the point where your blender is going to need an IP address unless you want an outdated smoothie. So of course in this day and age when computing and online interaction has become so pervasive that it would be of paramount importance to protect your networks, your devices and yourself. Not only is cyber space ubiquitous, but cyber attacks as well. Every day worldwide countless governments, companies, and private citizens are subject to cyber attacks. The security world works round the clock in an attempt to stay ahead of the attackers. One of the most important tools that helps the security tools stay ahead of would be attackers are honeypots.

Denial of Service also known as DoS is an attack that has been a part of cyber-attacks and cyber-terrorism for a long time. With the increase in the number of attacks on networks and websites, the need has come to implement better prevention systems to limit the number of attacks on the network. There are quite a few methods of countering these attacks that are already present but not a lot of networks have implemented them yet. This paper will talk about the different types of DoS attacks and their countermeasures. The paper will also talk about the advantages and

Internet Protocol version 6 (IPv6) is the next protocol version that it is used for communications on Internet. The Internet based on IPv4 protocol has made countless success in the past 20 years. Yet it has some limitations that were not estimated when it was first created, the IPv4 protocol cannot content the requirements of the Internet expanding. It is reported that all unallocated addresses for IPv4 will be used up within 5 to 6 years. IPv6 protocol suite was presented in IETF (Internet Engineer Task Force) on 1994. This suite is using 128-bit address instead of 32-bit IPv4 address. The United States, Europe, and East Asia were the first to recognize the significance of IPv6 and plan to deploy it. Transition to IPv6 has been documented as the most promising direction, because Ipv6 overcomes many of IPv4 limitations, and it is the only viable long-term replacement for IPv4.

The routing approach is the most prominent way for IPv6 multi-homing. The only drawback of this approach being the scalability issue. Every site that carries out multi-homing using the routing approach adds an entry to the global routing table, thereby making it a difficult choice for multi-homing, as far as scalability is concerned [5]. The different routing approach are as discussed below:

Internet protocol is a communication protocol which provides location and identification of computers on networks and routes traffic across the internet. IPV6 is the latest version of internet protocol. It was developed by internet engineering task force, when they are dealing with the IPV4 exhaustion problem. Every device in this world which is connected to the internet is assigned IP address for identification and its location. With rapid growth of technology, it became evident that we need more addresses for connecting various new devices in the future. In 1990s, Internet engineering task force has introduced IPV 6 to accommodate more addresses. IPV 4 uses only 32 bit addresses but IPV 6 addresses uses 128 bit addresses.

IPv6 has simplified packet header which makes packet processing more efficient. Unlike IPv4, Ipv6 contains no IP-level checksum. Thus, recalculating checksum at each router hop is not needed. It was achievable due to the fact

It is no doubt that almost everybody hears about IP address. Nowadays it is widely spread all over the world. IP address is shortened form of Internet Protocol (IP) address. A TCP/IP network is identified by IP address for device or computer. Internet and devices are connected with each other through IP protocol with sending information to each of them IP address. The IP address is not in computer, router, it is in field of interface. Nowadays we have got two types of IP address. These are IPv4( fourth generation of Internet protocol) and IPv6( sixth generation of Internet protocol).
