...back to the 1970’s. One specific task they have is to coordinate the global pool of IP and AS numbers providing them to Regional Internet Registries such as ARIN. The Asia Pacific Network Information Centre (APNIC) is an open, membership based, not-for-profit organization providing Internet addressing services to the Asia Pacific. The 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...

...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. DHCP servers in Linux can be configured to use IPv6: * Step 1: configure a fixed IPv6 address on your ethernet...

...Regional Internet Registry (RIR) for Canada, many Caribbean and North Atlantic islands, and the United States. ARIN manages the distribution of Internet number resources, including IPv4 and IPv6 address space and AS numbers. (Princeton.edu) The Internet Assigned Numbers Authority (IANA) is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. APNIC conducts extensive research into the depletion of the free pool of IPv4 addresses to predict timelines for IPv6 transition. There are approximately four billion IPv4 addresses, however not all of these can be used openly on the internet. (computerweekly) IPv6 allows 128 bits for IP address space, allowing 340282366920938463463374607431768211456 (three hundred forty undecillion) nodes to be uniquely identified on the Internet.(netbsd) In the past, there were a little over four billion IPv4 addresses made. Most people thought that this would be enough IP’s for the world. They didn’t realize how far the internet would come. IP’s are now household items just like refrigerators and in-door plumbing. I think at the current rate the IPv4 addresses will be exhausted within the next two to three years. Though they are still in use they are a finite resource. I think that we still use these because IPv6 has been completely finished or deployed. I don’t think that IPv4 can be hoarded because ARIN keeps a listing of all IP’s in use. This will allow them to track down what is in use and get...

...NT2640 Unit 8 – Assignment 1 – IPv6 Address Type – Multicast One of the most significant modifications in the general addressing model in IPv6 was a change to the basic types of addresses and how they were used. For example, the Broadcast addressing type has been eliminated in IPv6. Instead, support for multicast addressing has been expanded and made a required part of the protocol, and a new type of addressing called Anycast has been implemented. In IPv6, multicasting is used to allow a single device to send a datagram to a group of recipients, where IPv4 supported multicast addressing using the Class D address block in the “classful” addressing scheme. In IPv6, the well-known multicast addresses for the “All Nodes” (FF0x:0:0:0:0:0:1) and “All Routers” (FF0x:0:0:0:0:0:2) enable the equivalent function of what broadcast used to perform in IPv4. To send a message, either an “All Nodes” or “All Routers” multicast address is used along with the scope value to determine the scope (Node-Local, Link-Local or Site-Local) where messages are to be sent. Apart from the regular multicast address, each unicast address has a special multicast address called its solicited-node address. These solicited-node addresses are used by the IPv6 Neighbor Discovery (ND) Protocol to provide more efficient address resolution than the ARP method used in IPv4. When a host wants to get the layer two address of a datagram destination it sends a Neighbor Solicitation ICMPv6 message containing the...

...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 64bits...

Chapter 5, Review Question 4 Suppose two nodes start to transmit at the same time a packet of length L over a broadcast channel of rate R. Denote the propagation delay between the two nodes as dprop. Will there be a collision if dprop < L/R? Why or why not? No, there will be no collision. This is because the transmission time is less than the propagation delay; so the channel will be idle by the time transmission ends and the next propagation phase begins.

...document provides an analysis and comparison of IPv4 and IPv6 under various circumstances. It is well understood that IPv6 has been designed to replace IPv4. We have done a feature-by-feature comparison and contrast of IPv6 versus IPv4 and found that IPv6 offers many unique opportunities for increasing a network architectures efficiency and agility. In some sense, there is a competition going on between these protocols, as they are not directly compatible, and network providers and users are being forced to determine whether to support one or both protocols for various network services. The new version of IP,(i.e. IPv6), constitutes an effort to overcome the inborn limitations of IPv4, in order for the new protocol be able to respond to the new needs as they shape today in the Internet. This paper is aimed to discuss about various comparison issues when porting an IPv4 application to IPv6 with focus on issues that an application developer would face rather than a complete API reference.IPv4 is the incumbent and currently has the most widespread usage for conventional Internet applications.IPv6 is a large-scale re-design and re-engineering of IPv4, based on many lessons learned as the IPv4-based Internet grew and was used in unforeseen ways. Keywords-- IPv4, IPv6, Multicast, Quality of service (QOS), Routing. I. INTRODUCTION HE primary motivation for change arises from the limited address space.

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.

...4 and Version 6 Abstract The IPv4 used until now and still in use, has addresses of 32 bits fixed size. That would allow the use of approximately 4 billion addresses. Many assumptions are created regarding the year when the number of IPv4 addresses will drain, taking into the consideration the growth of the internet. The IPv6 would in other hand allow more addresses, since it is based on 128 bits addresses. As a result, preparations are ongoing to implement the IPv6. This paper will show the major aspects of ipv4 and ipv6 and how they are different and similar as well as examination of the IP address requirements and the methodology behind them.

...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, smartphones...

...William Kollie IS3120: Convergence of IP Based Network MR. McMiller July 20 2014 The dial up connection is made from a computer through modem and telephone line to the ISP's computer. The computer uses data in digital form. It means that it the computer can transmit data in 1's and 0's on and off also called digital or binary form. On other hand, telephone lines transmit data in analog form. It means that they transmit data by sound. the telephone line from your house is joined to a special terminal that sends the data received from their computers in form of audio signals from to enter the Public Switched Telephone Network PSTN. From PSTN, it is routed to the person or ISP that the modem is calling through the internet. Dial-up connection face connectivity problem which the user has to deal with. Dial up connection is unstable, dialup demand phone line connection which block incoming calls access, the chief disadvantage of dialup Internet, as compared with broadband Internet, is its slowness. Access to modern broadband networks is essential in the information age, said FCC Chairman Tom Wheeler. Yet 15 million Americans live in areas where they can’t get wireline broadband no matter how much they want it. These funds will jump-start broadband access in areas that would otherwise be bypassed by the digital economy.
