A common character-encoding standard that computers use to store, transmit, and print English (or “Latin”) text.
After many decades of use, the acronym ASCII (pronounced AS-KEE) is more well-known and more frequently used than its full name (American Standard Code for Information Interchange).
The encoding form produced by the Internationalized Domain Names in Applications (IDNA) protocol. IDNA uses the Punycode algorithm to generate an ASCII domain, known as an A-label, within the Domain Name System. ACE is used to encode Unicode strings for applications that cannot reliably handle values other than ASCII characters.
Asia Pacific Network Information Centre(APNIC)
Asia Pacific Top Level Domain Association(APTLD)
A nonprofit association of country code top-level domain (ccTLD) registries in the Asia Pacific region. APTLD provides a forum where its members can discuss policy matters affecting the ccTLD registries in their region. The association also serves as a channel of communication between its membership and Internet governance bodies such as ICANN.
Asian, Australasian, and Pacific Islands Regional At-Large Organization(APRALO)
The Regional At-Large Organization (RALO) that serves as the main forum and coordination point for public input to ICANN from the At-Large community in Asia, Australasia, and the Pacific Islands. APRALO keeps the At-Large Structures (ALSes) in its community informed about significant ICANN news. It also establishes mechanisms to facilitate two-way communication between the ALSes and ICANN policymakers, so ALS members can share their views on pending issues.
At-Large Advisory Committee(ALAC)
A certified body of volunteers within a Regional At-Large Organization (RALO) that represents the interests and concerns of individual Internet users. Working with its RALO, an ALS enables individuals to share their views on ICANN issues, help shape global ICANN policies, and conduct outreach and engagement.
The ALSes are wholly independent of ICANN. Groups that serve as ALSes include professional societies (e.g., engineers, lawyers), Internet Society chapters, community networks, and computer user groups.
In the New Generic Top-Level Domain Program (New gTLD Program), the net earnings from an auction held by ICANN to resolve string contention. These earnings are reserved and earmarked until the ICANN Board, in consultation with the ICANN community, determines a plan for the appropriate use of the proceeds.
authoritative name server
A Domain Name System (DNS) server that hosts the official database of resource records (the registry) for a DNS zone. The registry identifies the Internet Protocol (IP) addresses of the host servers (e.g., web servers, mail servers) and name servers in the authoritative name server’s zone. The resource records in its registry enable an authoritative name server to respond definitively to queries about the servers and subdomains within its zone.
To enable other computers to reach host servers within a domain, the domain must have one or more authoritative name servers. The name and IP addresses of those servers must also appear in the registry of the domain’s parent domain.
A code created by a registrar to help authenticate the registrant of a domain name in a generic top-level domain. The authorization code is a security measure to help prevent fraudulent or unauthorized transfers. This code is required for a registrant to transfer a domain name from one registrar to another.
Some registrars generate authorization codes for their registrants, and some allow registrants to generate their codes through a control panel on the registrar’s website. When registrants request an authorization code from the registrar, the registrar is obligated to provide the code within five days.
Auto-Renew Grace Period(AGP)
autonomous system number(ASN)
A globally unique identifier given to an autonomous system (AS). An AS is a collection of Internet Protocol (IP) networks operated by one or more network operators. When an Internet user sends a message to an IP address that exists outside the user’s own AS, routers forward the message to the AS in which the address resides. In this respect, the Internet uses ASNs to route messages between autonomous systems in much the same way postal systems use postal codes to route physical mail between geographic regions.
ASNs are allocated to network operators by Regional Internet Registries.
