A Record. Address Record. By adding an A Record line to a DNS listing, you are adding an address for a domain that resolves to more than one network interface. A Records are entered as an IP address (111.22.333.44) and have their own line in the DNS entry.
Administrative Contact. When registering a domain name, the administrative contact must be provided to the registrar when completing the registration form. The administrative contact is the individual who is responsible for acting as the primary contact. The administrative contact does not necessarily need to be able to manage the technical aspects of the domain.
Alias. One of several alternative hostnames with the same IP address.
Appraising. The process of evaluating a domain name and determining its market value.
Authoritative. A name server is considered authoritative for a domain name when it has the best source of information that can be found inside a given zone. Authoritative servers usually include a SOA (Start of Authority) record in their zone file for a domain name.

Backlinks. Incoming links to a website or web log. The number of backlinks is an indication of the popularity or importance of that website.
Bandwidth. The amount of data that can be transmitted at a given moment to a server. The higher your bandwidth the larger amount of traffic your site can handle at one time.

CGI. Short for Common Gateway Interface, a small script that processes data taken from the user such as from a form application or guestbook entry.
Change DNS Information. To make a new set of name servers responsible for resolving a domain name.
Change Registrar. To make a new registrar responsible for maintaining your ownership of a domain name.
CNAME (Canonical Name). A CNAME record maps an address to its canonical name. The name server handles CNAME records in a different manner than aliases are handled in the host table. When a name server looks up a name and finds a CNAME record, it replaces the name with the canonical name and looks up the new name.
Country Code Top Level Domain (ccTLD). Each country has a unique domain extension, usually a two letter abbreviation for the country. IANA is the organization responsible for overseeing the ccTLDs.
Contact Record/Contact ID. Contact Records or Contact IDs (sometimes called Agents) are individuals or groups who represent a registrant on matters related to the registrant's domain name(s). There are three types of Contacts: Administrative, Technical, and Billing. The entity listed as the Administrative, Technical, or Billing Contact is an individual or 'role' that is contacted in matters relating to the domain name. They also have the ability to Modify information pertaining to a domain name. A Contact may be a single person, a company, or organization.
Cookie. A unique identifier sent to a user's computer during a visit to a Web site. Cookies can be used to remember information such as user names and passwords (so a users don't have to enter them every time they visit a site) or to track future visits to a Web site.
Country Code Top Level Domain. 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). 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.
Cybersquatting. The practice of buying up domain names and "sitting" on them with the intent of making a large profit off the sell. Applies mostly to trademarks.

Domain Host. The business or registrar responsible for a domain name's server and keeping their web site "live."
Domain Name. A domain name is the core of your company's online identity. It is the address your customers will use to find information about your products and services on the web. Your domain name is yours entirely because once registered, no other party may use that identity online in that Top Level Domain. Domain Names always have 2 or more parts, separated by dots. The part on the left is the most specific, and the part on the right is the most general. A domain name can simply be thought of as your Internet address. The Internet uses Internet Protocol (IP) numbers to locate other computers. Internet users would typically have a hard time remembering these long strings of numbers to find sites. Domain names were developed to allow users to name these (IP) addresses with easy to remember names or phrases.
Domain Name System (DNS). The DNS maintains a relationship between IP addresses and domain names. DNS is composed of a set of database servers which maintain the relationship between IP addresses and domain names and facilitate the lookup between the two. Computers use the DNS system to electronically transmit data with other computers through the internet.
Domain Name Dispute A disagreement concerning the ownership of or legal right to a domain name. While domain name disputes are usually handled by ICANN, lawsuits involving domain names are becoming increasingly common in the courts.
Domain Name Dispute Resolution Policy. The ICANN policy which dictates how to resolve domain name disputes.
Domain Name Hosting. Maintaining the forwarding of a domain name and ensuring that it resolves.
Domain Name Record. An entry usually contained within a zone file.
Domain Name Registration The process of alloting a new, specific domain name to an owner.
Domain Parking. Registries require the use of name servers or hosts for every domain registered. In other words, every domain name has to be linked to a name server for it to be valid. Some people do not have their own name servers, therefore Domain Bank offers 'domain parking' (name parking) on its servers. It is a convenient way to hold or 'park' domain name(s) for an extended amount of time.
Dropped Domain. A previously registered domain name whose registration was allowed to lapse by the original owner (often times because the registration fees were not paid). A dropped domain is available for registration by the public.
Dynamic DNS. A DNS set up to allow users to attach a domain name to a server which uses a dynamic IP Address.
Dynamic IP Address. A variable IP address that is delegated to a computer or server each time it is connected to the Internet. Many ISPs use a dynamic IP address system in order to reduce the number of IP addresses they need to maintain. Each time a computer connects, it will be assigned an available IP address from the ISP's bank of IP addresses and will use that IP address until it disconnects. Use of this system greatly reduces the number of unused IP addresses at any given time, but, because a computer's address continually changes, a dynamic IP address system can cause difficulty in accessing a computer online.

Encrypted Password. A password that has been "scrambled" so that someone who is not intended to use that specific program/ or system will be denied.
Encryption. A very high security way to protect information that is sent over the Internet by scrambling the data so that only the person who is designated can read the information.

Local Name Server. A server, usually maintained by an ISP, that retrieves and stores domain information, such as hostnames and addresses. Local name servers cache resolved hostname information, so that the user may access infomration more quickly. This provides a faster retrieval of information, but can sometimes result in a display of old information.
