Provides an overview of IP addressing, the current standard IPv4 and the future standard of IPv6. Explains the limitations of IPv4 and the reasoning behind looking for an alternative IP addressing protocol. Addresses the advantages of the new IPv6 addressing technology with improved security, auto-configuration abilities, and improvement in routing. Explores mobile IPv6 features and the concerns with deploying IPv6 now and in the future. Studies Comcast as the first early-adopter of the technology and both their need for the adoption so early in the game and how they deployed the technology without interrupting service to customers. Investigates what steps need to be taken to deploy IPv6 with regard to current hardware still running IPv4, such as tunnels and translators like NAT64 and ALG. Also discusses the security risks and difficulties with deploying the technology right now with recommendations on how to avoid potential attackers through IPv6. Explains stateful and stateless automatic configurations, the new features of IPv6, and flow labels that IPv6 uses to increase efficiency by prioritizing data to devices that are on the same path.
Introduction to Internet Protocols

Every machine has a unique identifier that differentiates it from other machines on a network. This number is called the Internet Protocol address. There are two different standards for IP addresses, IPv4 and IPv6. IPv4 is the first version of the Internet Protocol address to be largely deployed, yet it is the fourth revision in the technology. IPv4 uses 32 binary bits to create a unique address on the network. When IPv4 was first created, it was used only on closed networks where computers rarely communicated outside the network. Since the Internet boom, many panicked because of the finite number of unique IPv4 IP addresses and saw it as limiting. That was until the IPv6…...

Ipv6 Is Inevitable

...IPv6 is inevitable Ever wonder how a computer reaches out to another computer? Ever wonder why it’s called an email address? The quick answer is that computers, much like our homes, have an address; better yet, an IP address. This is how a computer’s “mail” (data packets) is delivered. These addresses are right now known as IPv4 addresses. And much like real world addresses, they can be broken down the same way we do with addresses of apartment complexes and high rise buildings. But much like the limits of real world addressing, IPv4 is near reaching its limit. This will eventually lead us into the realm of IPv6. IPv4 is the current form of addressing being used for the Internet and TCP/IP data traffic. It consists of five classes (A, B, C, D, E), and uses a 32-bit structure broken down into four 8-bit octets. IPv4 gives up to 4.3 billion addresses. However, as we will find out later, that is quickly reaching its limit due to rapid growth of the internet. IPv6 a new form of addressing that uses a 128-bit address structure. This will greatly expand the possible number of users. The IPv6 address format uses hexadecimal addressing separated by colons instead of dotted decimal. It can give up to 340 undecillion addresses (340 with 36 zeros). But, it is not backwards compatible with IPv4. Currently, the number of vacant IPv4 addresses is down to 5%. Europe’s RIPE NCC (Reseaux IP Eutopeens Network Coordination Centre) expects to allocate the last of its addresses by midyear....

...IPv6 Jeremy Odom NT1430 Mr. McClain April 8, 2013 IPv6 What does IPv6 stand for? What exactly is IPv6? IPv6 stands for Internet Protocol version 6. IPv6 is the next generation internet protocol that is in the making of taking over the current internet protocol which is IPv4 or Internet Protocol version 4. 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......

...IPv6 Abstract Due to the overwhelming global response to the release of the internet there has been a diminished capacity of available network addresses. Although the internet community 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,......

...IPv6 First I would like to state that I have a bit of a beef with IPv6 and the IETF (Internet Engineering Task Force) for developing it the way they did. I’m not saying that I am smarter than they are or that a new version of the internet protocol isn’t very very needed, but why does the IPv6 format have to be hexadecimal. Numerical digits were working just fine and were pretty easy to memorize. Now network engineers have to find a way to either memorize or securely record eight four digit hexadecimal octets. I mean why not throw some wingding characters in the mix 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......

...IP v6 IPv6 or Internet Protocol Version 6 is currently the newest revision or version of the Internet Protocol. A type of communication protocol which is formal description of digital message formats; when communicating between computers using the internet connections. IPv6 is vastly similarly to IPv4 in many of its features still intact; providing different numerical IP addresses for internet compatible devices. IPv6 is considered the successor to IPv4 and to attend to the issues of IPv4. One of the major issues with IPv4 is that it utilizes 32-bits for the addresses it outlines, that is a fixed number; while being large in size many address are being taken over time will run out of addresses. IPv6 attempts to tackle this issue with its new feature, the utilization of 128-bits internet addresses. The IPv4 use 32 bits for the addresses it applies to internet devices, to determine how many IP this can provide is as simple as 2 to 32nd power which is about 4.30 billion unique addresses; these is the current amount of addresses for IPv4; still a fixed number. With steadily raising IP address being taken by our ever growing technology base world, our current demand for IP addresses is soon going to reach the limit at one point. The IETF or The Internet Engineering Task Force, decide to develop IPv6 to help address this issue before it becomes a major issue in the future. IPv6 is considerably larger in its unique address that it needs hexadecimal to help portray the unique......

...Brett Baker NT1430 Research Paper In this paper I am going to tell you about IPv6 and IPv4. Also going to let you know aout DHCP and a sample configuration for DCHP. We will look at the differences and the similarities between IPv6 and IPv4. Also will be looking at how DHCP can be configured in Linux. In the next couple paragraphs, you will see these listed. IPv4 is the fourth version of Internet protocol which uses 32 bit addressing whereas IPv6 is a next generation internet protocol which uses 128 bits addressing. IPv4 allows 4,294,967,296 unique addresses whereas IPv6 can hold 340-undecillion unique IP addresses. IPv4 address notation:, IPv6 addresses are denoted by eight groups of hexadecimal quartets separated by colons in between them. An example of a valid IPv6 address: 2001:cdba:0000:0000:0000:0000:3257:9652. (http://tianrunhe.wordpress.com/2012/04/25/compare-and-contrast-ipv4-and-ipv6/) When a DHCP client system connects to the network, dhclient requests a lease from the DHCP server and configures the client's network interface(s). Once a DHCP client has requested and established a lease, it stores information about the lease in a file nameddhclient.leases, which is stored in the /var/lib/dhclient directory. This information is used to reestablish a lease when either the server or the client needs to reboot. The DHCP client configuration file, /etc/dhclient.conf, is required only for custom configurations. The......

Ipv4 vs Ipv6`

...IPv4 vs. Ipv6 Internet Protocol (IP) is a set of technical rules that defines the network computer connections. There are two primary types of IP. Versions IP 4 and IP 6 IPv4 is the first version of IP to be the most used worldwide. This IP manages most of today’s internet traffic. There are over 4 billion IPv4 addresses, yet there are still not enough IP addresses for the world so something new had to be found. IPv6 is the next version of the growing and improving Internet Protocol. This was deployed in 1999. This new version meets the world’s IP addressing requirements for a very long time. The main difference between IPv4 and IPv6 are number of IP addresses each version contains. There are approximately 4,000,000,000 IP addresses in IPv4, which is 32bit. IPv6 has over 340,000,000,000,000,000,000,000,000,000,000,000,000 possible IP addresses because IPv6 is 128bit. Both versions work together with the Internet, but most all new IP addresses added to the Internet all come from IPv6 rather than IPv4 now because of the faster speeds and more options. IPv4 addresses are 32 bits long (4 bytes). The addresses are defined by host portion. The IP addresses are depended on address classes. In the 4,294,967,296 IPv4 addresses are available to the world; take the example IP address in the format 0000.0000.0000.0000 where each 0 could actually be a number from 0-9. IPv6 addresses are 128 bits long (16 bytes). Basic network architecture is defined as 64 bits and also hosts......

...IPv6 Protocol Text from presentation Sl2: Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) in 1998 (RFC2460) to deal with the long-anticipated problem of IPv4 address exhaustion. Sl3: Every device on the Internet must be assigned an IP address in order to communicate with other devices. With the ever-increasing number of new devices being connected to the Internet, the need arose for more addresses than IPv4 is able to accommodate. IPv6 uses a 128-bit address, allowing 2128, or 340×1036 addresses (340 undecillion addresses). IPv4 (32-bit address) allows only approximately 4.3 billion addresses. Sl5: The main advantages of IPv6: * Larger address space * Stateless address autoconfiguration (SLAAC) * Simplified processing by routers * Jumbograms Sl6: SLAAC IPv6 hosts can configure themselves automatically when connected to an IPv6 network using the Neighbor Discovery Protocol via Internet Control Message Protocol version 6 (ICMPv6) router discovery messages. When first connected to a network, a host sends a link-local router solicitation multicast request for its configuration parameters; routers respond to such a request with a router advertisement packet that contains Internet Layer configuration......

Unit 3 Ipv6 Addressing

...maximum number of potential IPv4 addresses is 4,294,967,926 and they are running out. IPv6 is being introduced to replace IPv4. There are potentially 340 trillion, 282 billion, 366 million, 920 thousand, 938 followed by 24 zeroes (also known as 2 to the power of 128) IPv6 addresses available. I think the world is running out of IPv4 addresses because almost everyone has one device or more that require an IP address. Also, some companies requested more IP addresses than they needed and they are sitting dormant waiting to be used. According to some estimates the IPv4 addresses will be depleted sometime within this year. Other estimates suggest 2037 as the year of depletion. APNIC ran out of IP addresses on 4/15/2011, IANA ran out of IP addresses on 2/3/2013 and a third estimate says that ARIN will run out on 3/22/2015. IPv6 has not gone mainstream yet because of Network Address Translation (NAT). NAT allows you to use a single IPv4 address for each office, regardless of the number of systems in the office, and also allows a network to have an IPv6 address outside the firewall. Many Internet service providers do not have a deadline for moving to IPv6 and some don’t even offer IPv6 addresses or services yet. Making the switch would require a software update and in some cases new hardware for some devices. Several of the older devices do not support IPv6 although some servers can support both IPv4 and IPv6 allowing the devices to talk to each other but it can contribute to the......
