The meaning of domain name extensions

by M. RoseThere are literally millions of domain name extensions on the Internet. These extensions also called Top Level Domains (TLD), function similar to the postal/ZIP code in your mailing address. The domain names provide an IP address that identifies the website associated with them. The IP address is used to assist the World Wide Web in locating the host server for retrieval and delivery of web pages, e-mails, and other web material.
Country-code domain name extensions (ccTLD) are associated with specific countries. Examples of country-code extensions are .fr (France), .ca (Canada), and .us (United States). There are more than 200 country-code extensions on the Internet. Some countries restrict the use of their codes, allowing for use only by host websites with servers within that country's territory. Almost half of the countries that hold registered domain name extensions are unrestricted, allowing use of its country-code extensions by websites with host servers anywhere in the world. You can find a complete list of country-code domain name extensions at (www.domainit.com/domains).
Global domain name extensions (gTLD) are generic; they can be used in any Uniform Resource Locator (URL) address regardless of the location of the website's host server. Some of the more common examples of global domain name extensions are .com (commercial), .net (networking organizations), .org (not-for-profit-organization), and .edu (educational institutions). These domain name extensions are associated with the type of business the host website is involved. You can find a comprehensive listing of global domain name extensions at (www.techdictionary.com/domain list).
Some websites use both country-code and global extensions. This is normally done in cases where the "host-business" is a multinational operation. In such cases the dual extension is used to distinguish the business's different locations of its operations. For example, Honda uses both a ccTLD and a gTLD to distinguish its European operation (www.honda.co.uk) from its Singapore operation (www.honda.com.sg).
The most frequently used (sometimes misused) TLD is the .com extension. This extension is used by many different types of e-businesses. It is also conveniently used by e-businesses that do not fit neatly into a specific category; for example, those businesses that engage in multiple products. It is also used to describe things not directly related to the e-commerce industries, such as the dot-com bubble. In this instance .com was used to describe the overvaluing of e-businesses on the stock market during the late 1900's. The dot-com burst refers to the subsequent failure of many these e-businesses.
The primary purpose of domain name extensions is to categorize and organize the multitude of websites on the Internet. One needs to look closely at the website before drawing a conclusion of the exact meaning of the domain name extension, since it is the host business that determines the use or misuse of the particular domain name extension used.
Name server
From Wikipedia, the free encyclopedia
Jump to: navigation, search
In computing, a name server (also spelled nameserver) consists of a program or computer server that implements a name-service protocol. It maps a human-recognizable identifier to a system-internal, often numeric, identification or addressing component.
For example, on the Internet, a special case of name servers, so called Domain Name System (DNS) servers, are used to translate a hostname or a domain name (for example, 'en.wikipedia.org') to its corresponding binary identifier (the IP address 145.97.39.155), or vice versa.

Also found in: Webster's Telecom Dictionary [edit] Authoritative name server
An authoritative name server is a name server that gives original, first-hand, definitive answers (authoritative answers) to DNS queries and not just cached answers that were obtained from another name server. Therefore it only returns answers to queries about domain names that are installed in its configuration system.
An authoritative name server can either be a master server or a slave server. A master server is a server that stores the original (master) copies of all zone records. A slave server uses an automatic updating mechanism of the DNS protocol in communication with its master to maintain an identical copy of the master records.
Every domain name must be assigned a set of authoritative name servers that are installed in NS records in the parent domain.
When domain names are registered with a domain name registrar their installation at the domain registry of a top level domain requires the assignment of a primary name server and at least one secondary name server. The requirement of multiple name servers aims to make the domain still functional even if one name server becomes inaccessible or inoperable.[4] The designation of a primary name server is solely determined by the priority given to the domain name registrar. For this purpose generally only the fully qualified domain name of the name server is required, unless the servers are contained in the registered domain, in which case the corresponding IP address is needed as well.
Primary name servers are often master name servers, while secondary name server may be implemented as slave servers.
