“The ccNSO is a body within the ICANN structure created for and by ccTLD managers.
Since its creation in 2003, the ccNSO has provided a forum for country code Top Level Domain (ccTLD) managers to meet and discuss topical issues of concern to ccTLDs from a global perspective and to share experiences. The variety of policies implemented by the ccTLDs facilitates the identification of best practice and cultural diversity.”
A class of top-level domain for countries and territories listed in the ISO 3166-1 lists. All ASCII ccTLD identifiers are two letters long, and all two-letter top-level domains are ccTLDs.
CNAME records can be used to alias one name to another. The DNS resolves the system’s domain name to its IP address, but sometimes more than one domain name resolves to the same IP address, and this is where the CNAME is useful. CNAME records can be used to alias one hostname to another, in contrast to an A record, which resolves a domain name to an IP address. A CNAME can be useful where you need multiple domain names to resolve to the same IP address: instead of setting up multiple A records, you can setup one of the domains (a.com) to resolve to the IP address as an A record, and set up the other domains as CNAME records pointing to a.com. This means that if the IP address ever needs to be changed, you only have to amend one A record.
A policy created through the GNSO policy development process listed in Annex A of the ICANN Bylaws. Consensus policies are binding on Registries and Registrars through their contracts. For more information, see the list of Consensus Policies that have been adopted by the ICANN Board of Directors.
“A Constituency is a formal interest group recognised by ICANN as representing a certain group of people and/or businesses that share a common perspective or interest pertaining to the domain name space. Constituencies have votes and shape a formal part of ICANN’s structure. For more information please refer to the GNSO’s Organizational Structure chart (https://icannwiki.org/Generic_Names_Supporting_Organization#/media/File:GNSO-Council.png) and ICANN’s Organizational Chart (https://www.icann.org/resources/pages/chart-2012-02-11-en)”.

The practice of registering domain names which may infringe third party rights.
Delegation refers to the delegation of responsibility by ICANN/IANA for administration of a TLD in the DNS root. The root zone is edited to include a new TLD, and the management of domain name registrations under such TLD is turned over to the Registry Operator. IANA manages the DNS root zone and the Root Zone Database provides the delegation details of all the TLDs.
The dispute mechanism for .uk domain names.
The 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 22.214.171.124, you can type www.internic.net. It is a “mnemonic” device that makes addresses easier to remember.
DNSSEC are a set of Internet Engineering Task Force (IETF) standards created to address vulnerabilities in the Domain Name System (DNS) and protect it from online threats.
Benchmarking is a service offering, introduced in late 2019, which assists Com Laude clients in taking a strategic approach to managing their domain portfolios. For more information please visit: https://comlaude.com/domain-benchmarking-podcast/.
A domain name is a text name or string of characters (e.g. comlaude.com) which provides a more memorable name to stand in for the address of a computer on the internet (which is typically a set of numbers, known as an IP address). Domain names must be unique. A web user can access a website by typing its domain name into the address bar of their web browser. Domain names are also used in email addresses to ensure an email is sent to the right person.
A dot brand domain is a new generic Top Level Domain that has been registered by a brand. Examples include: .gucci, .microsoft, .kpmg.
EPDPs are a GNSO policy function set out in the ICANN Bylaws used to establish Consensus Policy. They are the same as GNSO PDPs except they have a shorter scoping and issue identification phase.
ERRP is an ICANN policy covering the process we must take when a gTLD domain we manage is lapsing. The policy includes the email notifications we are required to send to the Registered Name Holder, the timing around interrupting delegation of the domain so that website and email no longer resolve, and the relevant time period and costs incurred should the Registered Name Holder wish to renew a domain that has gone past the expiration date without renewal.

The IANA is a division of ICANN. It is the authority originally responsible for overseeing IP address allocation, coordinating the assignment of protocol parameters provided for in internet technical standards, and managing the DNS, including delegating top-level domains, and overseeing the root name server system. Under ICANN, the IANA distributes addresses to the Regional Internet Registries, coordinates with the Internet Engineering Task Force and other technical bodies to assign protocol parameters, and oversees DNS operation.
ICANN manages the domain name system to ensure the operational stability of the internet. It is a California-incorporated, non-profit corporation that was created at the end of 1998 following the release of the NTIA Draft Proposal to Improve Technical Management of Internet Names and Addresses (Green Paper) and the NTIA Management of Internet Names and Addresses (White Paper). ICANN develops domain name policy through a bottom up, multi-stakeholder model.
A domain name including characters used in the local representation of scripts not written with the basic Latin alphabet (a-z). An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese.
New gTLD applications are reviewed by several panels of evaluators. During the Initial Evaluation the following assessments are completed: 1) String reviews and 2) Applicant reviews. String reviews consist of checks that the applied-for gTLD string is not expected to cause security or stability problems in the DNS. Applicant reviews include an assessment into whether the applicant has the necessary technical, operational and financial capabilities to operate a registry. For more information, consult the applicant guidebook – http://newgtlds.icann.org/en/applicants/agb.
An IP address is a numerical label assigned to a computer on the internet.
A Trademark Claims Service will be offered for a minimum of 90 days following sunrise in a new gTLD registry. The Claims Service will require registries to check new domain name registrations against the TMCH, and notify trademark owners and registrants when prospective registrations are identical to a mark.
The IPC is one of the Constituencies of the GNSO. They represent the interests of intellectual property owners worldwide and are particularly focussed on trademark and copyright concerns in the domain name system.

The Trademark PDDRP provides trademark holders the opportunity to seek redress from new gTLD Registry Operators exhibiting bad faith intent to profit from the systemic registration of infringing domain names. Remedies vary and may include termination of the registry contract by ICANN in extreme cases.
There are three different PDPs set out in the ICANN Bylaws: GNSO PDPs, GNSO EPDPs, ccNSO PDPs. The GNSO PDP and EPDP are where Consensus Policies are developed (these are binding on Registries and Registrars). Unless specified, GNSO PDPs apply to all gTLDs, not just new gTLDs.
Pre-delegation is a phase prior to delegation whereby applicants must complete a pre-delegation technical test to validate information submitted in their new gTLD application. This test must be passed by all new gTLD applicants before they are allowed to be introduced into the root zone.
Premium names are domain names that are held back from the sunrise process and can be allocated through auction or an RFP process rather than first come, first served. The cost of a premium domain name can be significantly larger than a typical domain purchase.

Bringing a complaint under the UDRP or other dispute mechanism in bad faith.
Registrants are the internet users who register domain names. Domain names must be registered through an ICANN-Accredited Registrar. Registrants do not interact directly with the Registry Operator. It is only gTLD domains that must be registered through an ICANN Accredited Registrar. With ccTLDs it is up to each ccTLD operator whether they only use Accredited Registrars or not.
An ICANN-accredited registrar is an entity that registrants use to register domain names. There are over 1500 ICANN accredited registrars in competition with each other. The registrar retains records containing technical and contact information that the registrants provide. These records are then submitted to the registry. The registrar has access to make changes to a registration by adding, deleting, or updating domain name records. It is only gTLD domains that must be registered through an ICANN Accredited Registrar. With ccTLDs it is up to each ccTLD operator whether they only use Accredited Registrars or not.
A registry is an authoritative master database of domain names registered in each top level domain. A Registry Operator maintains the master database of domain names for that registry. In addition, they produce the “zone files” that direct internet traffic to and from top level domains from any global location.
The agreement executed between ICANN and a registry operator pertaining to the operation of a gTLD.
The entity entering into the registry agreement with ICANN, responsible for the operation of the registry.
Any person or entity may submit a request for reconsideration or review of an ICANN action or inaction (“Reconsideration Request”), provided that the person/entity has been adversely affected by it. To protect against abuse of the reconsideration process, a request for reconsideration may be dismissed by the Reconsideration Committee.
The Redemption Grace Period helps resolve problems associated with domain name registration deletions caused by mistake, inadvertence, or fraud. When a domain name is deleted, a 30 day Deleted Name Redemption Grace Period will follow. This allows the registrant, registry, and/or registrar enough time to identify and amend any mistaken deletions. In this time the domain name will not function because it will have been removed from the zone. Succeeding the 30 day period, there is a 5-day period before a domain is finally deleted in order to notify all registrars of the deletion.
The root zone database represents the delegation details of top-level domains, including gTLDs and ccTLDs. As manager of the DNS root zone, IANA is responsible for coordinating these delegations in accordance with its policies and procedures. Please use this link to access the Root Zone database: https://www.iana.org/domains/root/db.
The RRA is the contract that governs the relationship between a Registry and an accredited Registrar. To offer a TLD a registrar will first be required to enter into a Registry-Registrar Agreement with the Registry Operator.

The RSSAC is an advisory committee to ICANN that advises the ICANN Board and community on matters relating to the operation, administration, security, and integrity of the Root Server System.
The Registries Stakeholder Group forms part of ICANN’s GNSO, representing the interests of gTLD registries in ICANN policy making.
SG are the bodies that comprise the Generic Names Supporting Organization, with each SG representing a different set of interests in the policy making process, e.g. Commercial SG (CSG), Non-Commercial SG (NCSG), Registrars SG (RrSG), and Registry SG (RySG). For more information please refer to the GNSO’s Organizational Structure chart (https://icannwiki.org/Generic_Names_Supporting_Organization#/media/File:GNSO-Council.png).
The ICANN Supporting Organizations (e.g. GNSO, ccNSO, etc.) are bodies within ICANN’s structure with the primary responsibility of developing and recommending substantive policies regarding those matters falling within their specific remit.
The SSAC advises the ICANN community and Board on matters relating to the security and integrity of the Internet’s naming and address allocation systems.
Standardised System for Access/Disclosure of domain registration data.
SSL is a networking protocol designed for securing connections between web clients and web servers.
Sunrise is a pre-launch phase providing trademark holders the opportunity to register domain names in a TLD before registration is generally available to the public. All new non-brand gTLD registries will have an obligation to provide a minimum 30 days notification of sunrise and then a 30-day sunrise period.
A registry that must collect and store the registrant, admin and tech details for a domain name. Example TLDs are .INFO and .BIZ; also, all new gTLDs are thick registries.
A registry where they are not required to collect all of the contact information for a domain. When performing a WHOIS lookup at a thin registry you will only see information related to the sponsoring registrar, nameservers, registration/expiration dates and the status of the domain. Example TLDs are .COM and .NET.
The TMCH is a global, central repository of trademark rights information to protect trademarks in the new gTLD program. It eliminates the need for brand owners to submit their trademark information to separate databases belonging to each registry.
Registering domain names which are close typographical varients of trade marked terms or brand names.
A policy for resolving disputes arising from alleged abusive registration of domain names (for example, cybersquatting), allowing expedited administrative proceedings that a trademark rights holder initiates by filing a complaint with an approved dispute resolution service provider.
The URS provides trademark holders with a rapid and efficient mechanism to “take down” undeniably infringing domain names. A successful proceeding will result in suspension of the domain name. Compliance with results is mandatory for all new gTLD operators. It is designed as a quicker and cheaper alternative to the UDRP, but only for clear-cut cases of infringement.
WHOIS provides public access to data associated with registered domain names. Databases can be queried that contain information such as registration and expiry dates, name servers, registrar information and registrant contact information. Following the adoption of the GDPR, the latter can be hidden to ensure the protection of the registrant’s privacy. Registrars must remind registrants to update, review and correct their WHOIS data at least once a year. Domain name registrations may be cancelled if the registrant provides false WHOIS data. (WHOIS will eventually be replaced by a new RDDS protocol, RDAP. Both WHOIS and RDAP are mechanisms for storing and disseminating the RDDS data.)
United Nations body devoted to the protection of intellectual property rights and an administrator of the UDRP.
The zone file contains all resource records associated with a domain name, and is stored on a DNS server maintained by the registry operator, i.e. the zone file for a TLD shows you a list of the domain names which are registered and delegated within that TLD.
