A short-term policy or specification that the ICANN Board of Directors can institute when it determines that an immediate action is necessary to maintain the stability or security of registrar services, registry services, the Domain Name System, or the Internet.
A numeric value in a resource record that indicates the length of time (in seconds) a resolver can keep the resource record in its cache. If a resolver queries its cache and receives a record whose TTL has elapsed, the resolver requests a new copy of the record from an authoritative name server.
A domain at the top of the naming hierarchy of the Domain Name System. In a domain name, the TLD appears after the second-level domain. For example, in the domain name icann.org, the characters org identify the TLD.
The administrators of a TLD control which second-level domains are recognized within the TLD. TLDs fall into two classes: generic top-level domains (e.g., .com, .net, .edu) and country code top-level domains (e.g., .jp, .de, .in).
During the Claims Period, registrants are alerted in real time if they attempt to register domain names that match trademarks in the Trademark Clearinghouse (TMCH). If the registrant chooses to proceed with the registration after receiving the alert, the Claims Service notifies the holder of the trademark.
A mechanism of the New Generic Top-Level Domain (gTLD) Program designed to help protect the rights of trademark holders. The Trademark Clearinghouse verifies and records rights information from all over the world. This verified information is used during domain name registration processes, especially when new gTLDs launch.
In the New Generic Top-Level Domain Program (New gTLD Program), a formal procedure that generally addresses a registry operator's alleged complicity in trademark infringement on the first or second level of a new gTLD.
Disputes resolved by a Trademark PDDRP are administered by Dispute Resolution Service Providers approved by ICANN. Complainants are required to take specific steps to address their issues before filing a formal complaint. An expert panel determines whether a registry operator is liable and recommends remedies to ICANN.
A trusted member of the Domain Name System’s technical and operational communities who has been selected to maintain custody of materials required for the successful operation of the root zone key signing key (KSK). By design, access to the KSK is spread across many individuals who must come together to operate the key. The TCRs play an essential role in securing the KSK and maintaining trust in the Domain Name System Security Extensions mechanism.
