How The Domain Name System is Maintained?
By Kathir | January 9, 2023
DNS stands for – Domain Name System is the directory of the Internet, where human approaches the internet to get their information through domain names. DNS was introduced by Paul Mockapetris in the year 1983, thus making people use names of anything instead of using the IP address to communicate to the Internet.
Where does DNS use?
As we know that the DNS is referred to as a Domain Name System, which was invented for the purpose of replacing the IP or Numbers with names to communicate with web browsers over the Internet. This term itself defines that the Domain Name System is a naming database in which the domain names are located and converted into an IP address.
For example, if someone search “SeekaHost.com” on a web browser, an internet server routes that name to the correspondent IP address, that’s the process that runs in the back end when you make a search in a web browser.

Do you know how the domain name system is maintained? The domain name system is maintained by the distributed database system.
DNS leans on two significant distinctions which are Nameserver and DNS records. The use of Nameserver is to undeniably store information on how to find DNS records. When a web browser or gateway makes a request for a domain, the nameserver for the domain used is to find the location and the details about the DNS records. In simple terms, a DNS record transformed the URL into an Ip address.
When a user types a domain name into their web browser, the browser sends a request to the DNS server to resolve the domain name into an IP address. The DNS server looks up the IP address in its database, which contains mappings of domain names to IP addresses. If the DNS server has the IP address in its database, it returns the IP address to the user’s browser.
If the DNS server does not have the IP address in its database, it sends a request to other DNS servers on the internet to try to find the IP address. Once the DNS server has found the IP address, it returns it to the user’s browser, which can then use the IP address to establish a connection with the server hosting the website.
The browser then sends a request to the server using the IP address, and the server sends back the content of the website to be displayed in the browser.
Without the DNS, we would need to remember the IP address of all the websites that we have necessary to visit. Gratefully, DNS servers handle this task for us so we can just type a domain name and connect to the website that we would like to visit.
