Name server A DNS name server is a server that stores the DNS records, such as address (A, AAAA) records, name server (NS) records, and mail exchanger (MX) records for a domain name (see also List of DNS record types) and responds with answers to queries against its database. name server indicates that its response is authoritative by setting the Authoritative Answer (AA) bit in the response to a query on a name for which it is authoritative. Name servers providing answers for which they are not authoritative (for example, name servers for parent zones) do not set the AA bit.

- Without DNS, the Internet would be an ugly place. DNS is one of the services responsible for directing network traffic based on name and numerical IP addresses. Specifically, it's the service that allows users to type in names instead of numbers to locate a Web site or Internet resource.he MSDN list of DNS standards documents is available at DNS Standards Documents. Information on DNS in Windows 2000 is available at Domain Name System (DNS) Center. Information on the Windows Server 2003 implementation of DNS can be found at Deploying DNS.

Domain Name System The Domain Name System is maintained by a distributed database system, which uses the client–server model. The nodes of this database are the name servers. Each domain has at least one authoritative DNS server that publishes information about that domain and the name servers of any domains subordinate to it.

Domain Name Service (DNS) A DNS server that has complete information for part of the DNS name space is said to be the authority for that part of the name space. This authoritative information is organized into units called zones, which are the main units of replication in DNS. A zone contains one or more RRs for one or more related DNS domains.

- A program, say a Web browser, that has a domain address usually needs to convert it into an IP address before making contact with the server. The domain name system (DNS) provides a mapping between IP addresses and domain names. All this information cannot be all in one place and so it is a distributed database.

What is Dynamic DNS? While DNS sounds like a truly great thing, it can be quite difficult to set up and is a lot of hassle if you just want people to connect to your home web server or gaming server so rather than go to the trouble, there are many companies that will do this for you for free by offering a service known as Dynamic DNS.NS is the process of transforming something that you understand-www.google.com-into something that the computer understands-in this case the IP Address 216.239.59.99 used to access the search engine on the main Google page.

DNS: The Magic that Translates Website Names into IP Addresses The DNS is a remarkable database. It doesn't perform its work alone, though. Things called Top Level Domains (TLDs) and root servers do a lot of the heavy lifting for the DNS. A Top Level Domain refers to the part of a domain name that comes after the period. For instance, the TLD of example.com is COM.

- DNS is an acronym for Domain Name Server, and is the system used to translate word-based addresses of systems (such as WWW.EXAMPLE.COM) to the numerical IP (Internet Protocol) address of the computer or system that should be located at that address.hen you use an alphanumeric address such as WWW.EXAMPLE.COM, your computer needs to understand what numerical IP addresses it needs to contact, and this is accomplished through DNS servers.
