...The History of IPv4 And Beginning of IPv6 Mathew J. Jones ITT Technical Institute IPv6 is the future of Internet Protocol, but first, it is important to recognize and identify IPv4 and talk a little about its history. The history of IPv6 is also something that needs to be discussed as even though it has not been implemented yet, it does have a brief history. Also, we can compare and contrast the two Internet Protocols with the advantages and disadvantages of both. There will also be mention of DHCP, and how DHCP servers can be configured to use IPv6. First, it is important to talk about the history of IPv4, but first IP’s, or Internet Protocol, main principle is routing network packets. This essentially creates internetworking, which establishes the Internet. In IP, or at the IP level, the main task is to deliver packets from the host to the destination host. But to do this the host and the destination host needs an address, and this is where IPv4 (and later IPv6) comes into play. IPv4 was then created to hand this, “In the 1980s, when the Internet went live to the public, IPv4 was the fourth revision of Internet Protocol, and the first offered to the public. IPv4 is the general standard of delivery of information between devices connected to the Internet.” (Dooly, 2013) After this, the Department of Defense eventually took on IPv4 as it’s own preferred method. It became the universal method of addressing of the world. IPv4 uses a 32-bit address of numbers and...

...was aware of this as early as the late 1980s it was not until the mid 1990s that they developed a solution known as IPv6 or Internet Protocol version 6. This updated version boasts many advantages but the transition process has been slow and there are many obstacles to full deployment. However, IPv6 must be deployed soon since there will be no address space left within IPv4. As access to the internet increases and a greater number of networks are created there is a need to create more address space on the web. Forecasters have predicted there will be a total depletion of IPv4 addresses sometime between 2010 and 2012 (Bradner, n.d.). However, there is relief in sight for the address exhausted IPv4 system, Internet Protocol version 6. This newer version has vastly expanded address space and new features to simplify the address assignment process. Although it was designed in the 1990s this system is still considered “new” and in 2008 was used less than 1% in internet enabled hosts in any country (IETF Tools, n.d.). In the late 1980s it became evident that there was a crunch on the number of addresses the IPv4 could assign. No one could have predicted that the internet would have gained the widespread popularity and accessibility that it has over the past three decades. However, in the 1990s IPv6 was introduced and in 1994 adopted by the Internet Engineering Task Force. At this time it was referred to as the IPng or Internet Protocol Next Generation. It was hoped that IPv6...

Continue reading to learn more about IPv6. “The current version of the Internet Protocol IPv4 was first developed in the 1970s, and the main protocol standard RFC 791 that governs IPv4 functionality was published in 1981. With the unprecedented expansion of Internet usage in recent years - especially by population dense countries like India and China. The impending shortage of address space (availability) was recognized by 1992 as a serious limiting factor to the continued usage of the Internet run on IPv4. With admirable foresight, the Internet Engineering Task Force (IETF) initiated as early as in 1994, the design and development of a suite of protocols and standards now known as Internet Protocol Version 6 (IPv6), as a worthy tool to phase out and supplant IPv4 over the coming years. There is an explosion of sorts in the number and range of IP capable devices that are being released in the market and the usage of these by an increasingly tech savvy global population. The new protocol aims to effectively support the ever-expanding Internet usage and functionality, and also address security concerns. IPv6 uses a128-bit address size compared with the 32-bit system used in IPv4 and will allow for as many as 3.4x1038 possible addresses, enough to cover every inhabitant on planet earth several times over. The 128-bit...

...too and while you’re at, let’s throw some different colors in. Could they make it any more difficult to remember? When it comes to Secret, Top Secret, TS/SCI, and above networks how are the network engineers supposed to build, maintain, and expand their networks at the same pace as with IPv4? I mean you can’t write the Secret IP’s or subnets down, well you’re not supposed to anyway. Of course they will have classified documents and network diagrams and notebooks, but that kind of stuff would have to be kept in a safe and you would have to go through a whole process just to take a look at your books. With all that said, I will have to give them credit for developing an IP format that will have a ton more addresses and will take so much longer to exhaust and is much more secure than its predecessor. Ok, with that part out of the way let’s take a look at the history of IPv6. The need for a new version of the so widely used internet protocol came out of the explosion of internet capable devices and the growing population of consumers that have or will have home computers, laptops, or any of a number of mobile wi-fi capable devices. The years which have passed since the publishing of IPv4 in 1981 has shown the IETF just how much and how quickly the number of IP addresses were being consumed....

...“With the growth of Internet, will IPv4 survive?” Note: Please focus on security, quality of service, and migration method. Introduction Humans are social who depend on the interaction with others for daily needs. Throughout human history, people some of them with few exceptions, have expended on the structure of various community networks for carrier, safety, food and companionship. Actually, people have been networked for a very long time. The ways in which humans interact are constantly changing. For this time being, sounds and gestures were all humans used to communicate is now replaced by the Internet which allows people share all types of communication such as documents, pictures, sound and video with billions of people near and far using computers. For the students and educational purposes the internet is widely used to gather information so as to do the research or add to the knowledge of any sort of subject they have. Even the business personals and the professions like lecturers, engineers doctors need to access the internet to filter the necessary information for their use. The internet is therefore the largest encyclopedia for everyone, in all age categories. Besides, not to forget internet is useful in providing with most of the fun these days such as games, social network service, instant messaging, networking conferences, video sharing or the online movies, songs, dramas and quizzes. In that, internet has provided people with a great opportunity to eradicate...

...Abstract Internet is global system of computer networks in which networks can brings users at any one computer to interact with other computer to get or give information, making video call, chatting with friends and so on. It also links together millions of businesses, government offices, educational institutions, and individuals. The history of internet began with the development of ARPA (Advanced Research Projects Agency) to build a networking project called ARPANET in 1969 by US Department of Defense also known as Pentagon. The original aims are to allow scientists at different locations to share info and collaborate on military and scientist projects. The advantages of ARPANET’s design was that, because messages could be routed or rerouted in more than one direction, the network could continue to function even if parts of it were destroyed in military attack or other disasters. Nowadays, the Internet has drastic control on culture and business with the rise of instance communication by electronic mail (Email), instant messaging, video calls and the World Wide Web (WWW) with its forums, blogs, social networking and online shopping sites. The internet continues to grow, driven by ever greater amounts of online information and knowledge, business, entertainment and social networking. According to Chuck Semeria, the Internet has entered the public awareness as the world’s largest public data network, doubling in size every nine months. This is because of the...

...Unit 1: Exploring DNS Kaplan University IT 530 July 2, 2013 Unit 1: Exploring DNS A domain name system (DNS) serves an important role for those who wish to access other networks, which includes websites. DNS allows for users to be able to be able to access Internet websites through a unique name rather than having to memorize a lengthy set of numbers and periods. In addition, DNS allows for the physical hosting location of a network or website to change transparently without anyone noticing. This is more commonly referred to as when a website changes hosts. Furthermore, DNS serves important functions related to mail by allowing users to connect, send, and receive email messages based off of the DNS of the mail server for a specific network (Karrenberg, 2004). Exploring Hierarchies All domains follow a certain hierarchy top to bottom hierarchy. The order for this hierarchy is: 1. root domain 2. top level 3. second level 4. sub-domain The root domain is a top-level domain that refers to the Internet. This is mostly maintained by ICANN, which is a private organization that maintain this area. ICANN manages the internet protocol addresses as well as the DNS root zones. ICANN also manages the DNS policy on naming abilities for top level domains ("INETDAEMON.com," 2013). The level that most users will first visibly notice when connecting to a domain through DNS is the top level domain. In this domain is the area where users will see .com, .net, and .org,...

...IP Addresses Classes and Special-Use IP Address Space History of IP Classes. When IP was first standardized in September 1981, the specification required that each system attached to an IP-based Internet be assigned a unique, 32-bit Internet address value. Systems that have interfaces to more than one network require a unique IP address for each network interface. To provide the flexibility required to support networks of varying sizes, the Internet designers decided that the IP address space should be divided into three address classes-Class A, Class B, and Class C. This is often referred to as classful addressing. Each class fixes the boundary between the network prefix and the host number at a different point within the 32-bit address. Class A Class A network address has an 8-bit network prefix, with the highest order bit set to 0 (zero) and a 7-bit network number, followed by a 24-bit host number. Today, Class A networks are referred to as “/8s” since they have an 8-bit network prefix. A maximum of 126 (27 -2) /8 networks can be defined. Each /8 supports a maximum of 224 -2 (16,777,214) hosts per network. Since the /8 address block contains 231 (2,147,483,648) individual addresses and the IPv4 address space contains a maximum of 232 (4,294,967,296) addresses, the /8 address space is 50 percent of the total IPv4 unicast address space. Class B Class B network address has a 16-bit network prefix, with the two highest order bits set to 1-0 and a 14-bit network number...

...IP Addresses Classes and Special-Use IP Address Space The history behind IP address classes can be dated back to September of 1981. With the standardization of IP, each system connected to an IP-based internet required a unique 32-bit internet address value. The first part of the address identifies the network that the host is present in, while the second part identifies that particular host. While more and more host machines are established on a particular network comes the need to properly identify each of them. All host connected to a network share the same network number (which is the first part of the address value) but must have a unique host number (second part). The only way hosts can share the same host number is if they are on 2 different networks. As years past more and more networks were established throughout the entire world. To handle the flexibility of growing networks, internet designers decided that IP address space should be divided into three address classes: Class A, Class B, and Class C. These three classes are the more publicly available classes and are the most well known. There are also two more classes that are not publicly available: classes D and E. These 2 classes are more for experimental purpose and are not issued publicly. Classes are determined by the first few binary bits of a IP address. These bits known as high-order bits are read by IP software to determine the logical network and host addresses for a device. Each class designates what...

...IPv4 Internet Protocol - A Brief History At the end of the 1960's there was a great demand in various US universities and research centers for a network that should permit nationwide utilization of existing computer resources. In addition to that there was the desire for data exchange. On the other hand there was the interest in practical experiences, design, implementation, the use of network techniques in general and packet switching in particular. So the Advanced Research Project Agency, an US government organization, started developing a net called ARPANET. From 1972 the Advanced Research Project Agency dealt with research projects of military interests and ARPANET was renamed DARPA. The first proposal was made in 1968. The contract was won in December 1968 by the company Bolt, Breakneck and Newman (BBN). The demands for file transfer, remote login and email were on top of the list for NCP (Network Control Protocol, the predecessor of TCP/IP). The first use of ARPANET was in 1971. In 1973, a project was started, developing new lower layer protocols because the existing layers had become functionally inadequate. So Cerf and Kahn specified the following goals for the lower layer protocols in 1974: • Independence from underlying network techniques and from the architecture of the host • Universal connectivity throughout the network • End-to-end acknowledgments • Standardized application protocols In 1981 the TCP/IPv4 was standardized in ARPANET RFC's.

...INTERNET INFRASTRUCTURE IN TURKEY Many things have changed since Arpanet. If we look to the 30 or 40 years back, we may be startled to see how much has changed in such a small span of time (and in such a fast way). The first thing that strikes our mind about this change is the "speed of the Internet": The first "backbone" had a bandwidth in 2 Kbps. Nowadays it has a bandwidth of 10 Gigabytes per second. We have mutliplied our speed 5-10 thousand times in the course of the time. Another example is the number of people using the computer Networks in Turkey. The Internet which was being used by only a few people 40 years ago, has now become the “network of networks” that has been shared by everybody and that embrace the world globally. Unfortunately there’s not much room for everyone on Internet. To solve this problem Internet Protocol is used which is basically a number allocation system that assigns a number to everyone. Every person, who will connect to the Internet or is already connected, has an IP number by default -to put it in more technical terms- has an "IP address" by default. If you’d like to have a space on Internet, the first thing you are to do is to find an IP adress from somewhere. For instance, if you are attending a University, most probably your department will assign you one. Then, how on earth your department has obtained that IP address from? Most probably, they have obtained the IP number from that university’s office for Information Technology...
