IPv4-IPv6 transition rolls out numerous challenges to the world of Internet as the Internet is drifting from IPv4 to IPv6. IETF recommends few transition techniques which includes dual stack and translation and tunneling. By means of tunneling the IPv6 packets over IPv4 UDP, Teredo maintains IPv4/IPv6 dual stack node in isolated IPv4 networks behindhand network address translation (NAT). However, the proposed tunneling protocol works with the symmetric and asymmetric NATs. In order to make a Teredo support several symmetric NATs along with several asymmetric NATs, we propose multifarious Sym Teredo (MTS), which is an extension of Teredo with a capability of navigating through several symmetric NATs. The work preserves the Teredo architecture and also offers a backward compatibility with the original Teredo protocol.

Ip Packet

The Internet Protocol (IP) version 4 (IPv4) has several known vulnerabilities. One of the important vulnerabilities is that the protocol does not validate the correctness of the source address carried in an IP packet. Users with malicious intentions may take advantage of this vulnerability and launch various attacks against a target host or a network. These attacks are popularly known as IP Address Spoofing attacks. One of the classical IP-spoofing attacks that cost several million dollars worldwide is the DNS-amplification attack. Currently, the availability of solutions is limited, proprietary, expensive, and requires expertise. The Internet is subjected to several other forms of amplification attacks happening every day. Even though IP-Spoofing is one of the well-researched areas since 2005, there is no holistic solution available to solve this problem from the gross-root. Also, every solution assumes that the attackers are always from outside networks. In this paper, we provide an efficient and scalable solution to solve the IP-Spoofing problem that arises from malicious or compromised inside hosts. We use a modified form of Network Address Translation (NAT) to build our solution framework. We call our framework as NAT++. The proposed infrastructure is robust, crypto-free, and easy to implement. Our simulation results have shown that the proposed NAT++ infrastructure does not consume more than the resources required by a simple NAT.

IPv4 and IPv6 will coexist for a long time, due to ISPes’ inertia in the transition from IPv4 to IPv6. Domain Name System (DNS) is a very important functional unit in the Internet. This paper describres the hierarchy and operating process of IPv6 DNS, IPv6 DNS resolver, and presents the DNS transition from IPv4 to IPv6 in particular. We suggest two methods to implement DNS service during the transition period: DNS-Application Level Gateway (DNS-ALG) with Network Address Translation-Protocol Translation (NAT-PT), and dual stacks. And we also propose their respective operational principles. This paper is of valuable reference for network engineers to construct DNS in the transition phase.

Internet protocol version 6 (IPv6) is the next generation Internet protocol proposed by the Internet Engineering Task Force (IETF) to supplant the current Internet protocol version 4 (IPv4). Lack of security below the application layer in IPv4 is one of the reasons why there is a need for a new IP. IPv6 has built-in support for the Internet protocol security protocol (IPSec). This chapter reports work done to evaluate implications of compulsory use of IPSec on dual stack IPv4/IPv6 environment.

The transition between the Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) will be a long process during both protocol coexists and it unreasonable to expect that many millions of IPv4 nodes will be converted overnight. Mobility is becoming ubiquitous nowadays. This paper has described about a background study of IPv4 and IPv6, the needs of IPv6, transition mechanisms in the various architectures, and comparison of the IPv4 and IPv6 in two major areas; header format and transition mechanism. Then, the transformation of IPv4 to IPv6 addressing by using tunnel and dual stack protocol will be discussed.

Key Features

With the explosion of the public Internet, corporate networks connected to the Internet, if not adequately secured, are vulnerable to damaging attacks. Hackers, viruses, worms, Trojan horses, and spyware try to invade privacy. This research examines how these threats affect the corporate network and ways to reduce them. MikroTik routerOS was configured as the router to examine these threats. Network Address Translation and packet filtering where the key features configured to make the network hidden for unauthorized users and filter unwanted traffics that might reflect malicious acts. The configuration and test were carried out at Iya Abubakar Computer Center, Ahamdu Bello University, Zaria, Nigeria. At the onset, the targeted network was full of virus, worms, Trojan horses, spyware, and vulnerable to unauthorized users. The signal strength of the network was usually very poor due to the effect from the threats affecting the bandwidth. The firewall was configured to filter out inherently dangerous services, exposing the network to fewer risks. After the research, the performance and efficiency of the network was improved tremendously.

Address Translation

Nowadays, many people will be used internet that for their work, communication, education, economic and organization necessary that is used today. Network address translation (NAT) is a method of remapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. A network is a system of hardware and software, put together for the purpose of communication and resource sharing. A network includes transmission hardware devise to interconnect transmission media and to control transmissions and software to decode and format data. The Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks. Knowledge on how the internet is able to communicate with internet users is a mystery to some people. Internet communication need to be TCP/IP protocol which means that TCP is Transmission Control Protocol, or what is sometimes simply used to refer to Internet Protocol, is the basic unit for communication on the internet. This can also be applied to private internet, like Ethernet and so on. Despite TCP and IP being used interchangeably, there is a slight difference between the two in relation to the roles they play IP is directly responsible for obtaining internet addresses and then it is the work of TCP to deliver the data obtained to the addresses achieved by IP. TCP/IP provides end-to-end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination. This paper aim is described operation and models of TCP-IP suite in data communication network.

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.
