The meaning of dns is an internet based network service that helps users locate a web page or website by converting hostnames into IP addresses. This is the most basic service available on the Internet and it allows billions of users to get the information that they need each day.
What is DNS?
The domain name system is an hierarchical database and network service which translates easily memorized domains names into numerical IP addresses required for Internet communication. It is a part of the Internet infrastructure and enables networks to identify computers, servers, applications, and other resources, regardless of their physical location.
It's a standard, hierarchical database which identifies all the information associated with domains in a way similar to how phone books translate a name into a number. The domain name system also identifies the information elements associated with email addresses, radio frequency identification tags, universal product codes, international characters in host names, and other Internet identifiers.
A record is made up of a collection of data elements, which are stored in a zone-file and specified in the DNS protocol. These data elements may be text-based, numeric or contain different fields to store various types of information.
Five primary record types exist: A, CNAME, MX, TXT, and SRV. There are a variety of other types, including those used to change a nameserver's IP address or the NS record that denotes which authoritative server is responsible for providing information about a domain.
NS records, or named server records, are records that indicate which authoritative name servers have responsibility for the domain. These records can be searched to locate a nameserver. In general, a domain has both a primary and a secondary name server.
A DNS resolver can be used to access authoritative name servers for each domain. These name servers maintain name and address data and are accessible from outside the domain. The DNS resolution process involves querying all the authoritative name servers, recursively or nonrecursively.
Clients send recursive queries to a resolver. This can be another DNS server, or a computer locally on the Internet. The DNS headers are used to negotiate recursive requests. They indicate whether the request is a nonrecursive one or if recursive. If recursive then they also include the name servers in the recursive.
The recursive question is compared with the response of the authoritative nameserver. If the answer is a match, then the recursive query is sent back to the client.
If the match is not found, then the query is sent on to a DNS Recursor. A DNS Recursor is a special server designed for receiving queries from clients via applications like web browsers. The recursor makes further requests to satisfy the query.
First, when an user performs a DNS query, they should check the cache of their browser. The cache contains the latest DNS records for all domains on the system. This reduces the number and complexity of network connections required to resolve a DNS request. The DNS recursor sends the request on to an IP address in order to locate the site or webpage.
