*Country Code Top Level Domain (ccTLD): A top-level domain containing a 2-character abbreviation as defined by ISO 3166-1 (Codes for the Representation of Names of Countries and Their Subdivisions). As of November 1999 there were 243 country code top level domains (ccTLDs) registered. Some examples are .us for the United States, .ca for Canada, .jp for Japan, .de for Germany, etc. ccTLDs are often contrasted to generic top level domains (gTLDs). ccTLDs often have more restrictive registration requirements including regional requirements whereas gTLDs tend to be open to all registrants around the world.

* Deactivation: The process of removing a domain name from the zone files for the top level domains. When a domain name is deactivated, the Domain Name System (DNS) will no longer have the information needed to resolve the domain name to its corresponding Internet Protocol (IP) number(s), effectively disabling the domain name as a tool for locating the related computers or organizations. InterNIC refers to this status as being "On Hold" . The domain name record, however, remains in InterNIC's domain name database.

* Deletion: The process of removing a domain name and its corresponding record from the Domain Name System (DNS) and InterNIC's domain name database. A deleted domain name cannot be used to locate computers on the Internet and will be made available for other parties to register on a first-come, first-served basis. A domain name may be deleted at the request of the domain name registrant, as a result of non-payment of fee, or due to circumstances particular to individual cases.

* Deleted Domain: A previously registered domain name whose registration has been cancelled by the registrar, possibly due to a dispute over ownership or a breach of contract. A dropped domain is available for registration by the public.

* Digital Signature: A piece of data that is attached to an electronic file that serves as the digital equivalent of a handwritten signature.

* Domain: A division of the entire space which holds domain names that characterizes a level of hierarchy in the domain name space and is indicated by a domain name.

* Domain Host: The business or registrar responsible for a domain name's server and keeping their web site "live" .

* Domain Monetization: It is a process of converting a domain name's traffic to money. A monetization company places ads on domain name Web Pages. Advertisers pay the monetization company a fee, which is currently based on pay-per-click (PPC), i.e., every time a visitor to the domain name clicks on a link, the domain name owner earns money.

* Domain Name: A domain-name is your own cyber-estate. This estate, just like its physical counterpart, has its value depending on its address (name) and its content. You can charge your visitors or give them a free tour, or run a side business as part of the estate. Just like a 5th Avenue address is limited and also is more valuable than the vast majority of other addresses, the value of your domain-name can vary from a few dollars to, well, some are going for a million dollars. We cannot tell you what furniture, art work, or side business to have on your cyber-estate, but your address would surely enhance the value of its content, or might actually destroy its value if the name doesn't attract clients. On a technical level,it is an addressing construct used for identifying and locating computers on the Internet. Domain names provide a system of easy-to-remember Internet addresses, which can be translated by the Domain Name System (DNS) into the numeric addresses (Internet Protocol (IP) numbers) used by the network. A domain name is hierarchical and often conveys information about the type of entity using the domain name. A domain name is simply a label that represents a domain, which is a subset of the total domain name space. Domain names at the same level of the hierarchy must be unique; for example there can be only one com at the top level of the hierarchy, and only one DomainMart.com at the next level of the hierarchy.
