Ipv4 to Ipv6 Implementation Challenges
IPv4 to IPv6: Challenges and Priority of IPv6 Implementation
Tyler Spellen
University of Maryland University College

Abstract
Regarding the Internet Layer protocol , IPv4 is currently the most widely deployed solution, being used by corporations and individual consumers around the world. While it has been identified that there are no more IPv4addresses available for allocation from the IANA (Internet Assigned Numbers Authority) to the five RIRs (Regional Internet Registries), many companies have still kept their IPv4 network infrastructure, deciding not to make the switch yet. So the question is, when does it make sense for a company to switch their network infrastructure from IPv4-only to IPv6 compatible, and what is the best way to execute this? Based upon in-depth research of this question using varied sources and case studies, a recommendation of implementation with tentative timeline for a given corporation will be made. Clear definitions and history of IPv4 and IPv6 will be provided. The purpose of this research paper is not to explain the IPv4 and IPv6 specifications in grave detail, but to give enough overview so that pressing issues associated with IPv6 deployment are understood. Gained efficiencies, security concerns, and competitive advantages associated with IPv6 implementation will be discussed. Answering this research question will give the reader additional insight into the challenges and priority of IPv6 implementation, helping to understand the significance, potential issues, and urgency concerning IPv6 deployment for corporations and individuals alike.

Introduction
For decades, the topic of IPv4 address exhaustion has been of concern to the IT community. The Internet Assigned Numbers Authority (IANA) is at the forefront of this topic, as they are responsible for the global IP address space management. On February 3, 2011, the NRO (Number Resource Organization) released an article, stating that the last two top level (/8)

    TCP/IP was first created from research projects by the United States Department of Defense (DOD), through the group called the Advanced Research Projects Agency (ARPA). Although IPv4 has worked well for many years, like all things it will be replaced by a better standard. IP version 6 (IPv6) will eventually replace IPv4 as the standard most commonly used. It has taken over a decade to migrate to IPv6, even though it was defined as a standard in the 1990s.…

    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.…

    In a computer network internet protocol is used for communication, to each device such as printers and computers a numerical label called an IP (Internet Protocol) Address is assigned. There are two functions of an IP Address a host or network interface identification, and also provides a location addressing. The basic elements of a network are the IP Address and Subnet Mask. There is also switching and routing which after you connect devices to switches and routers, data packets can be moved across the network. The Internet Protocol Version 4 (known as IPv4) is a protocol highly used even today, this IP Address consist of a 32-bit number in decimal or binary in four parts. In 1995 Internet Protocol Version 6 (known as IPv6) was created due to a high growth of the Internet, and the reduction of…

    Next Header (8 bits) The 8-bit Next Header field classifies the type of header proximately following the IPv6 header and placed at the start of the data field (payload) of the IPv6 packet. This field regularly specifies the transport layer protocol used by a packet's payload. The dual most mutual types of Next Headers are TCP (6) and UDP (17), but abundant other headers are also possible. The format approved for this field is the one anticipated for IPv4 by RFC 1700. In event of IPv6 protocol, the Next Header field is comparable to the IPv4 Protocol…

    Conventional subnet masking replaces the two-level IP addressing scheme with a more flexible three-level method; it lets network administrators assign IP addresses to hosts based on how they are connected in physical networks, subnetting is a real breakthrough for those maintaining large IP networks. It has its own weaknesses though, and still has room for improvement. The main weakness of conventional subnetting is in fact that the subnet ID represents only one additional hierarchical level in how IP addresses are interpreted and used for routing.…

    The designers of the Internet Protocol defined an IP address as a 32-bit number and this system, known as IPv4, is still in use today. However, due to the enormous growth of the Internet and the predicted depletion of available addresses, a new version IPv6, using 128 bits for the address, was developed in 1995. IPv6 was standardized as RFC 2460 in 1998, and its deployment has been ongoing since the mid-2000s.…
