The IPv4 came before the IPv6 and these datagrams are similar in many ways but also differ in more ways than one. IPv6 came out in the year 2004 and still uses many of the features that made IPv4 so successful. IPv6 is supposed to become the new standard over the older version of IPv6, but it is tough for v6 to take its spot when v6 cannot support everything v4 does, basically v6 cannot connect to a v4 system. Some differences are that it is stated that the IPv6 is more secure than the IPv4, the address size went from 32 bits in the IPv4 to 128 bits in the IPv6, extensible protocols are more flexible in the IPv6, IPv4 and IPv6 are not compatible, the IPv4 will not be able to support additional nodes or support for applications, and the threats are different for the IPv6 than the IPv4.
One reason why IPv6 is considered safer is that it uses 128 bits for its address which is also in hexadecimal. Having a bigger address means it takes longer time to find the address and having it in hexadecimal makes it even tougher to figure out. IPv6 also supports IPsec, which supports better security while sending data across the TCP/IP Network. IPv6 is considered safer because of the IPsec where in IPv4, there are many compatibility issues and without having the IPsec enabled, it can be a security fault. IPv6 includes security-orientated functionality by default whereas the IPv4 does not. Now some people might differ that the IPv6 is not more secure than IPv4 because of the poor allocation of the IPv6, the main issue with the security of the IPv4 was the address size being so small, but the IPv6 does have a larger address, it still has the potential to have problems, even though it may take a few thousand errors to conduct the error.
The address size of the IPv4 is to be 32 bits where it is in a regular format of an IP, example 192.168.23.157 whereas the IPv6 has a large…...

...that defines how computers communicate over a network. There are currently two versions: IP version 4 (IPv4) and IP version 6 (IPv6). IPv4 was the first version of Internet Protocol to be widely used, and accounts for most of today’s Internet traffic. There are just over 4 billion IPv4 addresses. While that is a lot of IP addresses, it is not enough to last forever. IPv6 is a newer numbering system that provides a much larger address pool than IPv4, amongst other features. It was deployed in 1999 and should meet the world’s IP addressing needs well into the future. The major difference between IPv4 and IPv6 is the number of IP addresses. There are 4,294,967,296 IPv4 addresses. In contrast, there are 340,282,366,920,938,463,463,374, 607,431,768,211,456 IPv6 addresses. IPv6 has many advantages compared with the older Internet protocol IPv4. The most useful advantages of IPv6 are address space extention, and simplified header format for efficient packet handling. Processing packets of IPv6 by routers is easier than processing packets of IPv4, because the hardware program knows in advance that the coming header is static in length. Thus the packet processing speed increases. There are three types of address in IPv6: anycast, unicast and multicast. In IPv4 there are unicast, broadcast, and multicast address. The anycast address is an additional address to IPv6, for sending the packet to the nearest node in the group, according to the routing protocol......

...connection to the Internet increases because it provides the organization with access to an ever expanding user population. By referring to the Realtimestatistics.org, the statistics of the Internet users in the world is 2,149,799,875 and rising in every minute. So the question is, with the rapid growth of Internet will IPv4 survive to provide the addressing to all the expanding billion users throughout the entire world or will it eventually exhaustion of the IPV4 address space. This paper will discuss about will or not the IPv4 survive in term of security, quality of services and migration method. Introduction The Internet Protocol (IP) is the protocol for data to be sent from one computer to another on the Internet. Each computer or host on the Internet has at least one IP address that uniquely identifies it from all other computers. IP address was designed to allow one computer to communicate with another via the Internet. By assign IP address to each device allow the location of literally billions of digital devices that are connected to the Internet to be pinpointed and differentiated from other devices. IPv4 stands for Internet Protocol version 4. It is the technology that makes it possible for us to connect our devices to the web. Whenever a device accesses the Internet, it is assigned a unique, numerical IP address such as 192.168.19.2.  To send data from one computer to another, a data packet must be transferred across......

Brief Description of Intercomunication Methods Between Ipv6 and Ipv4

...REDES DE AREA AMPLIA Tarea #4: IPv6 Abraham Rodrigo Díaz Mendoza. Mtro. Ing. David Rivera. Técnicas de transición de “IPvX a IPvY” (IPv6 a IPv4) Hay definido tres principales técnicas de transición. La primera (1) es la de doble pila de protocolos, un enfoque muy sencillo de implementar que requiere que los hosts y los routers soporten ambas versiones de IP y, por tanto, servicios y aplicaciones tanto IPv4 como IPv6. En estos momentos, este enfoque de doble pila es un mecanismo fundamental para introducir IPv6 en las arquitecturas IPv4 actuales y se prevé que siga siendo muy utilizado durante el próximo futuro. Para aquellos casos en que haya insuficientes direcciones IPv4 se ha definido una combinación del modelo de conversión y de doble pila de protocolos, conocido como DSTM (Dual Stack Transition Mechanism). La segunda (2) técnica se basa en tunneling, que permite, por ejemplo, interconectar las nubes IPv6 a través de un servicio IPv4 nativo por medio de un túnel. Los paquetes IPv6 son encapsulados por un router de extremo antes de ser transportado a través de la red IPv4, siendo des encapsulados en el extremo de la red IPv6 receptora. Los túneles pueden ser configurados estática o dinámicamente como “6to4” o “6over4”. Además, se ha propuesto TB (Tunnel Broker) para gestionar automáticamente y facilitar el proceso de configuración de las peticiones de túneles de los usuarios. ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) es un nuevo borrador Internet......

...IPv4 VS IPv6 IP (short for Internet Protocol) specifies the technical format of packets and the addressing scheme for computers to communicate over a network. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source. IP by itself can be compared to something like the postal system. It allows you to address a package and drop it in the system, but there's no direct link between you and the recipient. TCP/IP, on the other hand, establishes a connection between two hosts so that they can send messages back and forth for a period of time. There are currently two version of Internet Protocol (IP): IPv4 and a new version called IPv6. IPv6 is an evolutionary upgrade to the Internet Protocol. IPv6 will coexist with the older IPv4 for some time. IPv4 (Internet Protocol Version 4) is the fourth generation of the Internet Protocol (IP) used to identify devices on a network through an addressing system. The Internet Protocol is designed for use in interconnected systems of packet-switched computer communication networks. IPv4 is the most widely deployed Internet protocol used to connect devices to the Internet. IPv4 uses a 32-bit address scheme allowing for a total of 2^32 addresses (just over 4 billion addresses). With the growth of the Internet it is expected that the number of unused IPv4 addresses will eventually run out because every device including computers,......

The History of Ipv4 and Beginning of Ipv6

...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......

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......

...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......

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......

...the world. The original functions of IPv4 addresses were a part of the Transmission Control Protocol (TCP). As a formal protocol, IP was “born” when an early version of TCP developed in the 1970’s. This happened when predecessors of the internet were split into four layers, IP being the third layer. The key milestone in the development of the Internet Protocol was the publishing of RFC 791, Internet Protocol, in September 1981. This standard was a revision of RFC 760 in the previous year. The IP defined in RFC 791 was the first widely-used version of the Internet Protocol. However, most people would assume that the versions of IP that was the most widely used would be one, they are mistaken. The most widely used version of IP is version four which is where the name “IPv4” comes from. When you use IP today, you’re using IPv4. This version number is carried in the appropriate field of all IP datagrams. It was originally designed for internetwork a tiny fraction of the size of our current Internet, IPv4 has proven itself remarkably capable. Various additions and changes have been made over time to how IP is used, but the core protocol is basically the same as it was in the 80’s. Even though IPv4 is so amazing and so widely used development of a new IP has been underway since the mid 90’s. This eventually came up with IPv6 or otherwise known as IP Next Generation or IPng. IPv6 was created to supplement and eventually replace IPv4 in the next coming years. So many......

Ipv6 Multicast Address vs Ipv4 Broadcast

...IPv6 MULTICAST ADDRESS VS IPv4 BROADCAST Multicast enables you to send a single packet but still communicate with multiple systems on the network. Although IPv4 can employ multicast, in IPv6 multicast takes a much more prominent role. IPv6 does not have a broadcast address, which is not surprising considering the default subnet size is 2^64. Multicast is used in various ways to communicate with specific device groups, such as All Hosts on the local network or All Routers on the local network. In IPv6 all nodes are required to support multicast. Without multicast, many services that you need will simply not work. There’s a constant hum from the network on the multicast channels. When IPv4 was specified about 30 years ago, there was no multicast standard for IP networks initially. A lot of network services, like DHCP and ARP, had to depend on broadcast to work. IPv6 is a new protocol and had multicast services from start, so network discovery functions now builds upon multicast instead. This means that hosts that run these servers listen to the multicast addresses and other hosts will not be bothered when a client sends IP packets to these addresses. Multicast also enables site-wide and global services where clients subscribe to a data stream. ICMP messages to these multicast groups enable IPv6’s Neighbor Discovery to operate efficiently. Other groups include all DHCP Servers and all Mobile Agents. The increased reliance on multicast goes hand-in-hand with the increased......

Intro to Ipv4 & Ipv6

...Introduction to IPv4 & IPv6 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. 32 bits long (4 bytes). IPv4 is a classful logical addressing scheme using three primary address classes: Class A, Class B, and Class C. The class of the address is determined by the first number in the IP address. The total number of IPv4 addresses is 4, 294, 967,296. Address type: Unicast, multicast, and broadcast. IPv4 expressed in dotted decimal notation. The new concepts and new implementation of old concepts in IPv6 include the following: * Larger address space (128-bit vs. 32-bit) * Autoconfiguration of Internet-accessible addresses with or without DHCP (without DHCP it’s called stateless autoconfiguration) * More efficient IP header (fewer fields and no checksum) IPv4 allows 4,294,967,296 unique addresses whereas IPv6 can hold 340-undecillion (34, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000, 000) unique IP addresses. 128 bits long (16 bytes). Basic architecture is 64 bits for the network number and 64 bits for the host number. Often, the host portion of an IPv6 address (or part of it) will be a MAC address or other interface identifier. Address type: Unicast, multicast, and broadcast and anycast. IPv6 expressed in colon hexadecimal notation.

However IPv6 will be replacing that to meet the needs of the growing internet by providing many more addresses that are required to add more connection addresses to the internet. At the same time this is created to add more needed addresses IPv6 has improved the way the data is handled and processed with new security features. IPv4 to IPv6 to DNS IPv4 and IPv6 and how the differences between these two different Internet Protocols will change how the DNS connects systems over the internet. To understand these changes we will need to start from the beginning and breakdown what all these terms mean and how each works together to get a better understanding. What is an IP and how does it work? IP is short for Internet Protocol, and what that means in general is the address of a device or a machine. It could be viewed as a phone number or way to label a device or address in order to contact that machine or device in order to transfer data back and forth to that device. The first version of the Internet Protocol or IP was version 4 or IP4. It is a 32 bit address in that there are 4 numbers represented in a binary value of 8 bits for each of the 4 bytes comes to a total of......
