N

NaN-19 of 19 results

name collision

A situation where a name used in a private network, such as a corporate intranet, results in a query to the public Domain Name System (DNS). If the name from the private network matches a domain name in the DNS, the resolution of that name can produce adverse results.

name resolution

The process of transforming a domain name or hostname to its corresponding Internet Protocol (IP) address. When a user requests a domain or host server by name (e.g., www.icann.org), the Domain Name System resolves the requested name to its assigned IP address (e.g., 192.0.32.7).

Naming Services portal

An online service available through the ICANN website that provides a central location for contracted parties (e.g., contracted registry operators and accredited registrars) to conduct business with the ICANN organization. The portal helps streamline operational processes and is customized with community-requested features such as case tracking, multiuser company access, and structured workflows. Users of the portal can ask questions, submit information, and request approvals through the portal.

National Telecommunications and Information Administration(NTIA)

An agency of the United States Department of Commerce that is principally responsible for advising the Executive Branch on telecommunications and information policy issues.

When ICANN’s contract with NTIA expired on 1 October 2016, the coordination and management of the Internet’s unique identifiers transitioned to the global multistakeholder community.

Network Operators Group(NOG)

A professional association for individuals and groups involved in network architecture, engineering, or operations. NOG members come from entities such as Internet service providers, Regional Internet Registries, and network security groups. Through mailing lists and conferences, members exchange ideas, information, and best practices.

NOGs are usually geographically based (e.g., North American Network Operators Group, Australian Network Operators Group, Hong Kong Network Operators Group).

new generic top-level domain(new gTLD)

A gTLD that is introduced through the New Generic Top-Level Domain Program (new gTLD Program). This program aims to enhance innovation, competition, and consumer choice by enabling interested and qualified entities to establish new TLDs.

New Generic Top-Level Domain Program(New gTLD Program)

A program coordinated by ICANN to enable the expansion of the Domain Name System (DNS).

The final part of a domain name (e.g., .com, .net, or .org) represents a top-level domain (TLD). Under the New gTLD Program, entities can register TLDs with names such as .futbol, .istanbul, and .pizza, along with names in other alphabets (e.g., Arabic and Cyrillic) and languages (e.g., Chinese, Japanese, Korean).

The New gTLD Program aims to enhance innovation, competition, and consumer choice. Since the program began delegating new domains in 2013, over 1,300 new gTLDs have entered the Internet's root zone.

As part of the expansion of the namespace, the New gTLD Program has introduced several Rights Protection Mechanisms to safeguard intellectual property rights in the DNS. These mechanisms include the Trademark Clearinghouse (TMCH), which monitors domain registrations for trademark infringements, and Uniform Rapid Suspension (URS), which enables trademark holders to resolve infringement disputes outside the court system.

Newcomer program

A day-long learning session for people attending their first ICANN Public Meeting. During this highly interactive session, members of the ICANN organization and community share their experiences and expertise about ICANN and its work. Newcomers learn how to engage in ICANN’s multistakeholder model of policymaking and have an opportunity to network with others in the community.

Nominating Committee(NomCom)

The NomCom consists of 15 voting delegates along with a number of nonvoting leaders, advisors, and delegates.

The NomCom calls for applications from the ICANN community and evaluates candidates in a fair and consistent manner. The composition and responsibilities of the NomCom are described in the ICANN Bylaws.

non-ASCII

Referring to a character encoding standard other than ASCII. This term is often used to characterize a domain name or label that is not solely composed of ASCII characters (e.g., a non-ASCII domain name or a non-ASCII label).

Non-Contracted Parties House

A body within the Generic Names Supporting Organization Council that represents the interests of commercial and noncommercial entities. The Non-Contracted Parties House consists of representatives from the Commercial Stakeholder Group, the Noncommercial Stakeholder Group, and one voting member appointed by the ICANN Nominating Committee.

It also includes an NS record for each subdomain that has been delegated to other authoritative name servers. If a subdomain’s authoritative name server resides within the subdomain’s namespace, the zone file must include a glue record that provides the name server’s Internet Protocol (IP) address.
