Domain Name System
<networking> (DNS) A general-purpose distributed, replicated, data query service chiefly used on Internet for translating hostnames into Internet addresses. Also, the style of hostname used on the Internet, though such a name is properly called a fully qualified domain name. DNS can be configured to use a sequence of name servers, based on the domains in the name being looked for, until a match is found. The name resolution client (e.g. Unix's gethostbyname() library function) can be configured to search for host information in the following order: first in the local /etc/hosts file, second in NIS and third in DNS. This sequencing of Naming Services is sometimes called "name service switching". Under Solaris is configured in the file /etc/nsswitch.conf. DNS can be queried interactively using the command nslookup. It is defined in STD 13, RFC 1034, RFC 1035, RFC 1591. BIND is a common DNS server. Info from Virtual Office, Inc.. (2001-05-14) | ||||

Domain Name System (DNS)
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).

DNS - Domain Name Server or Domain Name System
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.

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.

Domain Name 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)

Domain name system
On the Internet, the Domain Name System (DNS) associates various sorts of information with so-called domain names; most importantly, it serves as the "phone book" for the Internet by translating human-readable computer hostnames, e.g. en.wikipedia.org, into the IP addresses, e.g. 66.230.200.100, that networking equipment needs for delivering information. It also stores other information such as the list of mail exchange servers that accept email for a given domain. In providing a worldwide keyword-based redirection service, the Domain Name System is an essential component of contemporary Internet use.
