Advisory Committee

An Advisory Committee is a formal advisory body made up of representatives from the Internet community to advise ICANN on a particular issue or policy area. Several are mandated by the ICANN Bylaws and others may be created as needed. Advisory committees have no legal authority to act for ICANN, but report their findings and make recommendations to the ICANN Board.

AfriNIC - The Afican Network Information Center

AfriNIC is a Regional Internet Registry (RIR), and is a non-profit membership organization responsible for the administration and registration of Internet Protocol (IP) addresses in the Africa region.

ALAC - At-Large Advisory Committee

ICANN's At-Large Advisory Committee (ALAC) is responsible for considering and providing advice on the activities of the ICANN, as they relate to the interests of individual Internet users (the "At-Large" community). ICANN, as a private sector, non-profit corporation with technical management responsibilities for the Internet's domain name and address system, will rely on the ALAC and its supporting infrastructure to involve and represent in ICANN a broad set of individual user interests.

On 31 October 2002, the ICANN Board adopted New Bylaws that establish the ALAC and authorize its supporting At-Large organizations. (Article XI, Section 2(4) of the New Bylaws.) The New Bylaws, which are the result of ICANN's 2002 reform process, went into effect on 15 December 2002. ALAC is to eventually consist of ten members selected by Regional At-Large Organizations, supplemented by five members selected by ICANN's Nominating Committee. To allow the ALAC to begin functioning immediately, the Transition Article of the Interim Bylaws provides for the Board to appoint ten members (two from each of ICANN's five regions) to an Interim ALAC.

Underpinning the ALAC will be a network of self-organizing, self-supporting At-Large Structures throughout the world involving individual Internet users at the local or issue level. The At-Large Structures (either existing organizations or newly formed for this purpose) will self-organize into five Regional At-Large Organizations (one in each ICANN region - Africa, Asia-Pacific, Europe, Latin America/Caribbean, and North America). The Regional At-Large Organizations will manage outreach and public involvement and will be the main forum and coordination point in each region for public input to ICANN.

APNIC - The Asia Pacific Network Information Centre

APNIC is a Regional Internet Registry (RIR), and is a non-profit membership organization responsible for the administration and registration of Internet Protocol (IP) addresses in the Asia-Pacific region, including Japan, Korea, China, and Australia.

ARIN - American Registry for Internet Numbers

ARIN is a Regional Internet Registry (RIR), and is a non-profit membership organization established for the purpose of the administration and registration of Internet Protocol (IP) addresses in North America, parts of the Caribbean, and sub-Saharan Africa.

ASO - Address Supporting Organization

The ASO advises the ICANN Board of Directors on policy issues relating to the allocation and management of Internet Protocol (IP) addresses. The ASO selects two Directors for the ICANN Board.

--------------------------------------------------------------------------------

ccNSO - The Country-Code Names Supporting Organization

The ccNSO is in the process of being established, with the ccNSO Assistance Group preparing the recommendations that are currently under discussion. Upon completion, the purpose of the ccNSO is to engage and provide leadership in activities relevant to country-code top-level domains (ccTLDs). This is achieved by 1) Developing policy recommendations to the ICANN Board, 2) Nurturing consensus across the ccNSO's community, including the name-related activities of ccTLDs; and 3) Coordinating with other ICANN SO's, Committees, or constituencies under ICANN. The ccNSO selects one person to serve on the board.

CCTLD - Country Code Top Level Domain

Two letter domains, such as .uk (United Kingdom), .de (Germany) and .jp (Japan) (for example), are called country code top level domains (ccTLDs) and correspond to a country, territory, or other geographic location. The rules and policies for registering domain names in the ccTLDs vary significantly and ccTLD registries limit use of the ccTLD to citizens of the corresponding country.

Some ICANN-accredited registrars provide registration services in the ccTLDs in addition to registering names in .biz, .com, .info, .name, .net and .org, however, ICANN does not specifically accredit registrars to provide ccTLD registration services.

For more information regarding registering names in ccTLDs, including a complete database of designated ccTLDs and managers, please refer to http://www.iana.org/cctld/cctld.htm.

--------------------------------------------------------------------------------

Domain Name Resolvers

Scattered across the Internet are thousands of computers - called "Domain Name Resolvers" or just plain "resolvers" - that routinely cache the information they receive from queries to the root servers. These resolvers are located strategically with Internet Service Providers (ISPs) or institutional networks. They are used to respond to a user's request to resolve a domain name - that is, to find the corresponding IP address.

DNS - Domain Name System

The Domain Name System (DNS) helps users to find their way around the Internet. Every computer on the Internet has a unique address - just like a telephone number - which is a rather complicated string of numbers. It is called its "IP address" (IP stands for "Internet Protocol"). IP Addresses are hard to remember. The DNS makes using the Internet easier by allowing a familiar string of letters (the "domain name") to be used instead of the arcane IP address. So instead of typing 207.151.159.3, you can type www.internic.net. It is a "mnemonic" device that makes addresses easier to remember.

--------------------------------------------------------------------------------

GAC - Governmental Advisory Committee

The GAC is an advisory committee comprising appointed representatives of national governments, multi-national governmental organizations and treaty organizations, and distinct economies. Its function is to advise the ICANN Board on matters of concern to governments. The GAC will operate as a forum for the discussion of government interests and concerns, including consumer interests. As an advisory committee, the GAC has no legal authority to act for ICANN, but will report its findings and recommendations to the ICANN Board. The Chairman of the GAC is Sharil Tarmizi of Malaysia. The Secretariat of the GAC is based at the European Commission.

gTLD - Generic Top Level Domain

Most TLDs with three or more characters are referred to as "generic" TLDs, or "gTLDs". They can be subdivided into two types, "sponsored" TLDs (sTLDs) and "unsponsored TLDs (uTLDs), as described in more detail below.

In the 1980s, seven gTLDs (.com, .edu, .gov, .int, .mil, .net, and .org) were created. Domain names may be registered in three of these (.com, .net, and .org) without restriction; the other four have limited purposes.

Over the next twelve years, various discussions occurred concerning additional gTLDs, leading to the selection in November 2000 of seven new TLDs for introduction. These were introduced in 2001 and 2002. Four of the new TLDs (.biz, .info, .name, and .pro) are unsponsored. The other three new TLDs (.aero, .coop, and .museum) are sponsored.

Generally speaking, an unsponsored TLD operates under policies established by the global Internet community directly through the ICANN process, while a sponsored TLD is a specialized TLD that has a sponsor representing the narrower community that is most affected by the TLD. The sponsor thus carries out delegated policy-formulation responsibilities over many matters concerning the TLD.

A Sponsor is an organization to which is delegated some defined ongoing policy-formulation authority regarding the manner in which a particular sponsored TLD is operated. The sponsored TLD has a Charter, which defines the purpose for which the sponsored TLD has been created and will be operated. The Sponsor is responsible for developing policies on the delegated topics so that the TLD is operated for the benefit of a defined group of stakeholders, known as the Sponsored TLD Community, that are most directly interested in the operation of the TLD. The Sponsor also is responsible for selecting the registry operator and to varying degrees for establishing the roles played by registrars and their relationship with the registry operator. The Sponsor must exercise its delegated authority according to fairness standards and in a manner that is representative of the Sponsored TLD Community.

GNSO - Generic Names Supporting Organization

The GNSO is the successor to the responsibilities of the Domain Name Supporting Organization (DNSO; see below) that relate to the generic top-level domains.

The GNSO is the body of six constituencies, as follows: the Commercial and Business constituency, the gTLD Registry constituency, the ISP constituency, the non-commercial constituency, the registrar's constituency, and the IP constituency.

--------------------------------------------------------------------------------

IANA - Internet Assigned Numbers Authority

The IANA is the authority originally responsible for the oversight of IP address allocation, the coordination of the assignment of protocol parameters provided for in Internet technical standards, and the management of the DNS, including the delegation of top-level domains and oversight of the root name server system. Under ICANN, the IANA continues to distribute addresses to the Regional Internet Registries, coordinate with the IETF and others to assign protocol parameters, and oversee the operation of the DNS.

ICANN - The Internet Corporation for Assigned Names and Numbers

The Internet Corporation for Assigned Names and Numbers (ICANN) is an internationally organized, non-profit corporation that has responsibility for Internet Protocol (IP) address space allocation, protocol identifier assignment, generic (gTLD) and country code (ccTLD) Top-Level Domain name system management, and root server system management functions. Originally, the Internet Assigned Numbers Authority (IANA) and other entities performed these services under U.S. Government contract. ICANN now performs the IANA function. As a private-public partnership, ICANN is dedicated to preserving the operational stability of the Internet; to promoting competition; to achieving broad representation of global Internet communities; and to developing policy appropriate to its mission through bottom-up, consensus-based processes. The DNS translates the domain name you type into the corresponding IP address, and connects you to your desired website. The DNS also enables email to function properly, so the email you send will reach the intended recipient.

IDNs - Internationalized Domain Names

Internationalized Domain Names, or IDNs, are web addresses in your own language. Many efforts are underway in the Internet community to make domain names available in character sets other than ASCII. These "internationalized domain name" (IDN) efforts were the subject of a 25 September 2000 resolution by the ICANN Board of Directors, in which it recognized "that it is important that the Internet evolve to be more accessible to those who do not use the ASCII character set," but stressed that "the internationalization of the Internet's domain name system must be accomplished through standards that are open, non-proprietary, and fully compatible with the Internet's existing end-to-end model and that preserve globally unique naming in a universally resolvable public name space."

IETF - Internet Engineering Task Force

The IETF is a large open international community of network designers, operators, vendors, and researchers concerned with the evolution of the Internet architecture and the smooth operation of the Internet. It is open to any interested individual.

IP - Internet Protocol

The communications protocol underlying the Internet, IP allows large, geographically diverse networks of computers to communicate with each other quickly and economically over a variety of physical links. An Internet Protocol Address is the numerical address by which a location in the Internet is identified. Computers on the Internet use IP addresses to route traffic and establish connections among themselves; people generally use the human-friendly names made possible by the Domain Name System.

ISOC - The Internet Society

The Internet Society is the international organization for global cooperation and coordination for the Internet and its internetworking technologies and applications. ISOC membership is open to any interested person.

ISP - Internet Service Provider

An ISP is a company, which provides access to the Internet to organizations and/or individuals. Access services provided by ISPs may include web hosting, email, VoIP (voice over IP), and support for many other applications.

LACNIC - Latin American and Caribbean Internet Addresses Registry

LACNIC is a Regional Internet Registry (RIR) for Latin America and the Caribbean.

RGP - Redemption Grace Period

Problems and complaints relating to deletion of domain-name registrations are very common. Businesses and consumers are losing the rights to their domain names through registration deletions caused by mistake, inadvertence, or fraud. Current procedures for correcting these mistakes have proven inadequate. To move toward a solution to these problems ICANN developed the RGP.

How it works:

Now, the "delete" of a domain name (whether inside or outside of any applicable grace period) will result in a 30-day Deleted Name Redemption Grace Period. This grace period will allow the domain name registrant, registrar, and/or registry time to detect and correct any mistaken deletions.

During this 30-day period, the deleted name will be placed on REGISTRY-HOLD, which will cause the name to be removed from the zone. (The domain name will not function/resolve.) This feature will help ensure notice to the registrant that the name is subject to deletion at the end of the RGP, even if the contact data the registrar has for the registrant is no longer accurate.

During the Redemption Grace Period, registrants can redeem their registrations through registrars. Registrars would redeem the name in the registry for the original registrant by paying renewal fees, plus a service charge, to the registry operator. Any party requesting redemption would be required to prove its identity as the original registrant of the name.

After the 30-day period when the domain name can be redeemed, there is a 5-day period when the domain essentially is pending deletion. This timeframe is implemented to facilitate notice to all registrars before a domain is finally deleted.

Registrar

Domain names ending with .aero, .biz, .com, .coop, .info, .museum, .name, .net, .org, and .pro can be registered through many different companies (known as "registrars") that compete with one another. A listing of these companies appears in the Accredited Registrar Directory.

The registrar you choose will ask you to provide various contact and technical information that makes up the registration. The registrar will then keep records of the contact information and submit the technical information to a central directory known as the "registry." This registry provides other computers on the Internet the information necessary to send you e-mail or to find your web site. You will also be required to enter a registration contract with the registrar, which sets forth the terms under which your registration is accepted and will be maintained.

Registry

The "Registry" is the authoritative, master database of all domain names registered in each Top Level Domain. The registry operator keeps the master database and also generates the "zone file" which allows computers to route Internet traffic to and from top-level domains anywhere in the world. Internet users don't interact directly with the registry operator; users can register names in TLDs including .biz, .com, .info, .net, .name, .org by using an ICANN-Accredited Registrar.

RIR - Regional Internet Registry

There are currently five RIRs: AfriNIC, APNIC, ARIN, LACNIC and RIPE NCC. These non-profit organizations are responsible for distributing IP addresses on a regional level to Internet service providers and local registries.

RIPE and RIPE NCC - Réseaux IP Européens

RIPE is an open and voluntary organization, which consists of European Internet service providers. The RIPE NCC acts as the Regional Internet Registry (RIR) for Europe and surrounding areas, performs coordination activities for the organizations participating in RIPE, and allocates blocks of IP address space to its Local Internet Registries (LIRs), which then assign the addresses to end-users.

Root Servers

The root servers contain the IP addresses of all the TLD registries - both the global registries such as .com, .org, etc. and the 244 country-specific registries such as .fr (France), .cn (China), etc. This is critical information. If the information is not 100% correct or if it is ambiguous, it might not be possible to locate a key registry on the Internet. In DNS parlance, the information must be unique and authentic.

--------------------------------------------------------------------------------

SESAC - Security and Stability Advisory Committee

The President's standing committee on the security and stability of the Internet's naming and address allocation systems. Their charter includes a focus on risk analysis and auditing. SESAC consists of approximately 20 technical experts from industry and academia as well as operators of Internet root servers, registrars, and TLD registries.

SO - Supporting Organizations

The SOs are the three specialized advisory bodies that will advise the ICANN Board of Directors on issues relating to domain names (GNSO and CCNSO) and, IP addresses (ASO).

--------------------------------------------------------------------------------

TLD - Top-level Domain

TLDs are the names at the top of the DNS naming hierarchy. They appear in domain names as the string of letters following the last (rightmost) ".", such as "net" in "www.example.net". The administrator for a TLD controls what second-level names are recognized in that TLD. The administrators of the "root domain" or "root zone" control what TLDs are recognized by the DNS. Commonly used TLDs include .com, .net, .edu, .jp, .de, etc.

--------------------------------------------------------------------------------

UDRP - Uniform Dispute Resolution Policy

All ICANN-accredited registrars follow a uniform dispute resolution policy. Under that policy, disputes over entitlement to a domain-name registration are ordinarily resolved by court litigation between the parties claiming rights to the registration. Once the courts rule who is entitled to the registration, the registrar will implement that ruling. In disputes arising from registrations allegedly made abusively (such as "cybersquatting" and cyberpiracy"), the uniform policy provides an expedited administrative procedure to allow the dispute to be resolved without the cost and delays often encountered in court litigation. In these cases, you can invoke the administrative procedure by filing a complaint with one of the dispute-resolution service providers.

For more details on the UDRP, see the ICANN UDRP page and the FAQs.

--------------------------------------------------------------------------------

W3C - World Wide Web Consortium

The W3C is an international industry consortium founded in October 1994 to develop common protocols that promote the evolution of the World Wide Web and ensure its interoperability. Services provided by the Consortium include: a repository of information about the World Wide Web for developers and users; reference code implementations to embody and promote standards; and various prototype and sample applications to demonstrate use of new technology.

WIPO - World Intellectual Property Organization

WIPO is an intergovernmental organization based in Geneva, Switzerland responsible for the promotion of the protection of intellectual rights throughout the world. It is one of the 16 specialized agencies of the United Nations system of organizations.

WHOIS

Information about who is responsible for domain names is publicly available to allow rapid resolution of technical problems and to permit enforcement of consumer protection, trademark, and other laws. The registrar will make this information available to the public on a "Whois" site. It is however possible to register a domain in the name of a third party, as long as they agree to accept responsibility -- ask your registrar for further details.
