Sebastian Möller, Technische Universität Berlin Gutachterin: Prof. Anja Feldmann, Ph.D., Technische Universität Berlin Gutachter: Prof. Vern Paxson, Ph.D., University of California, Berkeley Gutachter: Prof. Steve Uhlig, Ph.D., Queen Mary University of London Tag der wissenschaftlichen Aussprache: 2. August 2017 Berlin 2017 Abstract IP addresses are essential resources for communication over the Internet. In IP version 4, an address is represented by 32 bits in the IPv4 header; hence there is a finite pool of roughly 4B addresses available. The Internet now faces a fundamental resource scarcity problem: The exhaustion of the available IPv4 address space. In 2011, the Internet Assigned Numbers Authority (IANA) depleted its pool of available IPv4 addresses. IPv4 scarcity is now reality. In the subsequent years, IPv4 address scarcity has started to put substantial economic pressure on the networks that form the Internet. The pools of available IPv4 addresses are mostly depleted and today network operators have to find new ways to satisfy their ongoing demand for IPv4 addresses. Mitigating IPv4 scarcity is not optional, but mandatory: Networks facing address shortage have to take action in order to be able to accommodate additional subscribers and customers. Thus, if not confronted, IPv4 scarcity has the potential to hinder further growth of the Internet.

Initially discouraged and only “last resort” (imperfect). Today no other choice! • Expect to use them in combination! - 2 Dual-Stack Approach • When adding IPv6 to a system, do not delete IPv4 – This multi-protocol approach is familiar and well-understood (e.g., for AppleTalk, IPX, etc.) – In the majority of the cases, IPv6 is be bundled with all the OS release, not an extra-cost add-on • Applications (or libraries) choose IP version to use – when initiating, based on DNS response: • if (dest has AAAA record) use IPv6, else use IPv4 – when responding, based on version of initiating packet • This allows indefinite co-existence of IPv4 and IPv6, and gradual app-by-app upgrades to IPv6 usage • A6 record is experimental - 3 Dual-Stack Approach IPv6 IPv6 IPv4 IPv4 Application Application Application Application TCP/UDP TCP/UDP TCP/UDP IPv6 IPv6 IPv4 IPv4 IPv6-only stack Dual-stack (IPv4 & IPv6) IPv4-only stack IPv6

Even the most optimistic forecast of IPv6 uptake for Book Review the global Internet is measured in years rather than months following exhaustion, and the more pessimistic forecasts extend into multiple decades.

  • Empirical Analysis of Ipv4 and Ipv6 Networks Through Dual-Stack Sites
    information Article Empirical Analysis of IPv4 and IPv6 Networks through Dual-Stack Sites Kwun-Hung Li and Kin-Yeung Wong * School of Science and Technology, The Open University of Hong Kong, Hong Kong, China; [email protected] * Correspondence: [email protected] Abstract: IPv6 is the most recent version of the Internet Protocol (IP), which can solve the problem of IPv4 address exhaustion and allow the growth of the Internet (particularly in the era of the Internet of Things). IPv6 networks have been deployed for more than a decade, and the deployment is still growing every year. This empirical study was conducted from the perspective of end users to evaluate IPv6 and IPv4 performance by sending probing traffic to 1792 dual-stack sites around the world. Connectivity, packet loss, hop count, round-trip time (RTT), and throughput were used as performance metrics. The results show that, compared with IPv4, IPv6 has better connectivity, lower packet loss, and similar hop count. However, compared with IPv4, it has higher latency and lower throughput. We compared our results with previous studies conducted in 2004, 2007, and 2014 to investigate the improvement of IPv6 networks. The results of the past 16 years have shown that the connectivity of IPv6 has increased by 1–4%, and the IPv6 RTT (194.85 ms) has been greatly reduced, but it is still longer than IPv4 (163.72 ms). The throughput of IPv6 is still lower than that of IPv4. Keywords: IPv6; IPv4; network performance; Internet; IoT Citation: Li, K.-H.; Wong, K.-Y. Empirical Analysis of IPv4 and IPv6 1.

  • Ipv4 Exhaustion, Ipv6 Transition
    Potential Impacts on Communications from IPv4 Exhaustion & IPv6 Transition Robert Cannon FCC Staff Working Paper 3 Federal Communications Commission Washington, DC 20554 December 2010 FCC Staff Working Papers are intended to stimulate discussion and critical comment within the FCC, as well as outside the agency, on issues that may affect communications policy. The analyses and conclusions set forth are those of the authors and do not necessarily reflect the view of the FCC, other Commission staff members, or any Commissioner. Given the preliminary character of some titles, it is advisable to check with the authors before quoting or referencing these working papers in other publications. Recent titles are listed at the end of this paper and all titles are available on the FCC website at http://www.fcc.gov/papers/. Abstract The Internet is in transition. The original address space, IPv4, is nearly exhausted; the Internet is in the progress of migrating to the new IPv6 address space. The Internet Protocol version 4 (IPv4) developed in the late 1970s has the capacity for about 4 billion unique addresses. It would have been hard to imagine in the 1970s that 4 billion addresses were not going to be enough. But by the early 1990s, Internet engineers recognized that the supply of addresses was relatively limited compared to likely demand, and they set to work designing a successor to IPv4. They developed a new Internet Protocol, IPv6, with a vastly increased address space: 340 trillion trillion trillion addresses. Broadband Internet access has become essential to the United States and the rest of the world.
