Domain Name Service

Domain Name Service; a system that maps user-friendly computer host and domain names (e.g., host.domain.com) to IP addresses (e.g., 204.162.86.58). Like telephone numbers, IP addresses uniquely identify computers on the Internet for addressing messages. See also host name, domain, and IP address.

Domain Name System (IETF) 

Directory Name Service

The online distributed database system that (a) is used to map human-readable addresses into Internet Protocol (IP) addresses, (b) has servers throughout the Internet to implement hierarchical addressing that allows a site administrator to assign machine names and addresses, (c) supports separate mappings between mail destinations and IP addresses, and (d) uses domain names that (i) consist of a sequence of names, i.e., labels, separated by periods, i.e., dots, (ii) usually are used to name Internet host computers uniquely, (iii) are hierarchical, and (iv) are processed from right to left, such as the host nic.ddn.mil has a name (nic -- the Network Information Center), a subdomain (ddn -- the Defense Data Network), and a primary domain (mil -- the MILNET).

Domain Name Service/Server

Domain Name System. A mechanism used in the Internet for translating names of host computers into addresses. The DNS also allows host computers not directly on the Internet to have registered names in the same style.

Domain Naming System

The name lookup the Internet uses to convert from alphabetic names such as www.gemplus.com to 32-bit binary IP addresses. See TCP/IP , Country Codes , Domain Name .

The Domain Name System is how the Internet links together the thousands of Networks that it is comprised of. The DNS is utilised whenever you send an Email or access a particular Web Page . Each computer on the Internet has a one of more Domain Names such as "fredbloggs.co.uk". The .co indicates a commercial organisation & the .uk indicates that the computer is in the United Kingdom.
Standard conventions used in Domain Names include:-
ac - Educational institution
co - Commercial organisation
com - Commercial organisation
edu - Educational institution
gov - Non military government organisations
int - International Organisations
mil - Military government organisations
net - Networks
org - non profit organisation
You will also see these codes in URL's such as
"homepages.enterprise.net/jenko/Glossary/G.htm".

These DNS converts the Domain Names to a unique number known as an IP address (the IP stands for Internet Protocol). You will often see the IP address displayed by your Web Browser when you are connecting to a particular computer.

A Domain Name Server  maps IP numbers  to a more easily remembered name. When you type http://www.webguest.com  into your browser , the DNS (specified when you installed dial-up networking) searchs for a matching IP address (208.28.202.95). If the DNS doesn't find an entry in its database, it will ask other DNSs until the entry is found, and you will see our site. Otherwise, you'll get an error message from your browser.

An acronym for Domain Name Server, DNS refers to a database of Internet names and addresses which translates the names to the official Internet Protocol numbers and vice versa.

Abbreviation for Domain Name System. A distributed client-server database system which links domain names with their numerical IP adresses.

See: Domain Name System

The DNS is a general purpose distributed, replicated, data query service. The principal use is the lookup of host IP addresses based on host names. The style of host names now used in the Internet is called "domain name", because they are the style of names used to look up anything in the DNS. Some important domains are: .COM (commercial), .EDU (educational), .NET (network operations), .GOV (U.S. government), and .MIL (U.S. military). Most countries also have a domain. For example, .US (United States), .UK (United Kingdom), .AU (Australia). It is defined in STD 13, RFCs 1034 and 1035. See also: Fully Qualified Domain Name.

DNS (Digital Nervous System ) or ( Domain Name System )
The DNS translates URL text addresses into a numeric internet address(such as dem.com to 125.23.7.167).

Allows users to relate to computers on the internet by using textual addresses(eg.www.plnet.net)for ease of use,rather than the IP Address system.

(DNS) The unique name of a collection of computers connected to networks such as the Internet. A general-purpose, replicated, distributed data query service for looking up host IP addresses based on host names. The DNS is hierarchical, consisting of domains, subdomains, sites, and hosts. Unique names are formed from smallest to largest, and are of the form user@host.site.subdomain.domain, where host and site are often optional. On the Internet, domain names typically end with a suffix denoting the type of site:

.com (commercial)
.edu (educational)
.net (network operations)
.gov (US government)
.mil (US military)
.org (organization)
.us (United States)
.ca (Canada)
.uk (United Kingdom)
.au (Australia)
.cz (Czech Republic)
.xx (where xx refers to another country's two-letter abbreviation)

Stands for "Domain Name System." The primary purpose of DNS is to keep Web surfers sane. Without DNS, we'd have to remember the IP address of every site we wanted to visit, as opposed to just the name. Now, I have some computer science friends who might prefer this, but for normal people, names are much easier to remember. The reason for the Domain Name System is that web sites are acutally located by their IP addresses. So, when you type in "http://www.adobe.com", the computer doesn't immediately know that it should look for Adobe's web site. Instead, it sends a request to the nearest DNS server, which matches an IP address to the domain name and then connects you to the server with that IP number. And we just take it for granted.
