DNS- Domain Name Server.<\/li>\n
In 1983 Domain Name Server was introduced by Paul Mockapetris and Jon Postell.<\/li>\n
Through internet it is a naming system for all the resources which includes physical nodes and applications.<\/li>\n
It is used to locate the resource through network easily.<\/li>\n
Domain Name Serveris an internet which maps the domain names to their associated IP addresses.<\/li>\n
Without Domain Name Server, users must know the IP address of the web page that you wanted to access.<\/li>\n
If we want to visit particular website, then the user will type the website into the address bar of the web browser.<\/li>\n
Once the domain name is entered, then the domain system will translate the domain name into the IP address which can be easily interpreted by the computer.<\/li>\n
The computer can locate the web page requested by the user, by using the IP address.<\/li>\n
In Domain Name Server there are four servers work with each other to get the correct IP address to the client.<\/li>\n
They are DNS recursor, Root nameservers, TLD nameservers, Authoritative nameservers.<\/li>\n
DNS recursor also known as DNS resolver which receives the query from the DNS client and communicates with other DNS servers to find the right IP address.<\/li>\n
Root nameservers answers requests by sending back a list of the authoritative nameservers that go with the correct Top-level Domain.<\/li>\n
Top-level Domain nameserver keeps the IP address of the second-level domain contained within the TLD name then it releases the website\u2019s IP address and sends the query to the domain\u2019s nameserver.<\/li>\n
Authoritative nameserver\u00a0gives you the real answer to your Domain Name Server query.<\/li>\n<\/ul>\n
