  • The Future of Internet Governance: Should the United States Relinquish Its Authority Over ICANN?
    The Future of Internet Governance: Should the United States Relinquish Its Authority over ICANN? Lennard G. Kruger Specialist in Science and Technology Policy September 1, 2016 Congressional Research Service 7-5700 www.crs.gov R44022 The Future of Internet Governance: Should the U.S. Relinquish Its Authority over ICANN Summary Currently, the U.S. government retains limited authority over the Internet’s domain name system, primarily through the Internet Assigned Numbers Authority (IANA) functions contract between the National Telecommunications and Information Administration (NTIA) and the Internet Corporation for Assigned Names and Numbers (ICANN). By virtue of the IANA functions contract, the NTIA exerts a legacy authority and stewardship over ICANN, and arguably has more influence over ICANN and the domain name system (DNS) than other national governments. Currently the IANA functions contract with NTIA expires on September 30, 2016. However, NTIA has the flexibility to extend the contract for any period through September 2019. On March 14, 2014, NTIA announced the intention to transition its stewardship role and procedural authority over key Internet domain name functions to the global Internet multistakeholder community. To accomplish this transition, NTIA asked ICANN to convene interested global Internet stakeholders to develop a transition proposal. NTIA stated that it would not accept any transition proposal that would replace the NTIA role with a government-led or an intergovernmental organization solution. For two years, Internet stakeholders were engaged in a process to develop a transition proposal that will meet NTIA’s criteria. On March 10, 2016, the ICANN Board formally accepted the multistakeholder community’s transition plan and transmitted that plan to NTIA for approval.

  • IANA Report on Recognition of Afrinic As a Regional Internet Registry
    IANA Report Subject: Recognition of AfriNIC as a Regional Internet Registry Date: 6 April 2005 The Internet Assigned Numbers Authority (the IANA), as part of the administrative functions associated with management of the Internet Protocol (IP) address space, is responsible for evaluating applications for approval of new Regional Internet Registries. ICANN has received an application for final approval and recognition of the African Internet Numbers Registry (AfriNIC) as the fifth Regional Internet Registry (RIR). Background The role and responsibilities of ICANN/IANA in this area are defined in the Address Supporting Organization Memorandum of Understanding <http://www.icann.org/aso/aso- mou-29oct04.htm> (ASO MOU), and ICP-2 <http://www.icann.org/icp/icp-2.htm> ("Criteria for Establishment of New Regional Internet Registries"). In September 2004, an application was submitted by the AfriNIC organization for recognition, together with a detailed transition which included draft bylaws, policies, funding model, and staff resumes. On request of the ICANN President, the IANA staff conducted a preliminary evaluation. In September 2004 the President reported to the Board his conclusion that the application and transition plan constituted a reasonable basis for eventual recognition, though he noted that some adjustments would be necessary. Also in September 2004, the existing RIRs, APNIC, ARIN, LACNIC and RIPE NCC, through the Number Resource Organization (NRO), issued a statement expressing their ongoing and continuing support for AfriNIC, and recommending a favorable response to the application by recognizing AfriNIC's accomplishments thus far. Consistent with the IANA©s preliminary evaluation and the recommendations of the existing RIRs, the ICANN Board on 30 September 2004 gave provisional approval <http://www.icann.org/minutes/resolutions-30sep04.htm> to the AfriNIC application, with the expectation that the transition plan would be completed and an amended or revised application for recognition would be submitted.

  • Ipv6 – What Is It, Why Is It Important, and Who Is in Charge? … Answers to Common Questions from Policy Makers, Executives and Other Non­Technical Readers
    IPv6 – What is it, why is it important, and who is in charge? … answers to common questions from policy makers, executives and other non­technical readers. A factual paper prepared for and endorsed by the Chief Executive Officers of ICANN and all the Regional Internet Registries, October 2009. 1. What is IPv6? “IP” is the Internet Protocol, the set of digital communication codes which underlies the Internet infrastructure. IP allows the flow of packets of data between any pair of points on the network, providing the basic service upon which the entire Internet is built. Without IP, the Internet as we know it would not exist. Currently the Internet makes use of IP version 4, or IPv4, which is now reaching the limits of its capacity to address additional devices. IPv6 is the “next generation” of IP, which provides a vastly expanded address space. Using IPv6, the Internet will be able to grow to millions of times its current size, in terms of the numbers of people, devices and objects connected to it1. 2. Just how big is IPv6? To answer this question, we must compare the IPv6 address architecture with that of IPv4. The IPv4 address has 32 bits, allowing today’s Internet to connect up to around four billion devices. By contrast, IPv6 has an address of 128 bits. Because each additional bit doubles the size of the address space, an extra 96 bits increases the theoretical size of the address space by many trillions of times. For comparison, if IPv4 were represented as a golf ball, then IPv6 would be approaching the size of the Sun.2 IPv6 is certainly not infinite, but it is not going to run out any time soon.

  • 9 China and Global Internet Governance a Tiger by the Tail
    9 China and Global Internet Governance A Tiger by the Tail Milton L. Mueller As of June 2010 the Chinese government claimed the country’ s number of “ netizens, ” or Internet users, had increased to 430 million. 1 That very large number is only 32 percent of China ’ s total population. 2 Already one of the biggest presences on the Internet, and with a long way to go yet, China and the Internet enjoy a complex and seemingly paradoxical relationship. Many Westerners have trouble making sense of the way China ’ s socialist market economy (SME) combines heavy restrictions with vibrant growth, and globalized networking with an insistence on territorial sover- eignty. Western observers have long abandoned the notion that the Internet was inherently uncontrollable and that its use would automatically overthrow dictator- ships. They are now replacing that simplistic notion with an equally coarse inversion: the image of China as the constructor of an impregnable “ Great Firewall, ” a place of omnipotent surveillance, a population susceptible to well-organized propaganda cam- paigns, and a source of pervasive and insidious cyber attacks and cyber espionage. It is a new Internet version of the Cold War. The Internet in the People ’ s Republic of China (PRC) strains and challenges the capacity of the Chinese Communist Party (CCP) to maintain control. And the fact that China needs to be linked to the external world, through the Internet as well as through trade, provides a double challenge. The international environment of Internet governance is freer, is private-sector based, and is more capitalistic than China ’ s rulers would prefer.

    INTERNET SOCIETY COMMENTS SUBMITTED TO THE UNITED STATES DEPARTMENT OF COMMERCE, NATIONAL TELECOMMUNICATIONS AND INFORMATION ADMINISTRATION, NOTICE OF INQUIRY “ASSESSMENT OF THE TRANSITION OF THE TECHNICAL COORDINATION AND MANAGEMENT OF THE INTERNET'S DOMAIN NAME AND ADDRESSING SYSTEM [DOCKET NO. 090420688-9689-01]” The Internet Society provides the following comments in response to the National Telecommunications and Information Administration Notice of Inquiry “Assessment of the Transition of the Technical Coordination and Management of the Internet's Domain Name and Addressing System [Docket No. 090420688- 9689-01].” The NOI raises fundamental questions about the management of the Internet Domain Name System, and specifically about the Domain Name Project that has been ongoing since 1997. The NOI background material and questions go to the heart of how the Internetʼs naming and numbering functions operate. In the context of the NOI, the Internet Society offers the following recommendations for consideration. Overall recommendation: Conclude the Joint Project Agreement The Internet Society recommends that the Joint Project Agreement be concluded, and that we declare a successful end to the DNS Project. A thorough review of the 1998 Green Paper, White Paper, and the successive versions of the Memorandum of Understanding (MOU) between the United States Department of Commerce and ICANN concerning the DNS Project reaffirms the original US government goal “to privatize the management of the domain name system (DNS) in a manner that increases competition and facilitates international participation in its management.” Privatization is to take place “based on the principles of stability, competition, private, bottom-up coordination, and representation.” The government also clearly set out the reasons for the approach it took to the DNS Project: “A private coordinating process is likely to be more flexible than government and to move rapidly enough to meet the changing needs of the Internet and of Internet users.

Use of Geographic Terms in Domain Names 2 Introduction to Digital Governance No one person, government, organization, or company governs the digital infrastructure, economy, or society. Digital governance is achieved through the collaborations of multi-stakeholder experts acting through polycentric communities, institutions, and platforms across national, regional, and global spheres. Digital governance may be stratified into three layers: 1. Economic and Societal Layer 2. Logistical Layer 3. Infrastructure Layer 3 Digital Governance https://www.icann.org/news/multimedia/1563 4 Names, Numbers, Protocols Names are the combination of text that we type into a browser. Numbers are the numbers linked to the text. Protocols are the international standards for lookups, queries, and responses. 5 Names, Numbers, Protocols Protocols guide the coordination of names with numbers. This process serves as the road map for an inquiry from point A to point B. • Data is broken into packets and packets reconstructed at their destination. • Addresses are looked up, queries are made as to whether the address is correct, and a response or “no” is sent. • If one “no,” then no resolution. 5 The Root Root Zone/Root Services • 12 organizations from four countries • Administer 13 different root servers • Provide top-level DNS services via hundreds of machines around the world 6 What is IANA?
