Before reading this article, you might want to know what domain names are and how do they work? If you don’t know about it, then you can get a clear concept about it in this article.
What is DNS?
The Domain Name System(DNS); maps human-readable domain names (in URLs or in an email address) to IP addresses, for instance, DNS translates and maps the domain https://dnskart.com to the IP address 104.26.2.33.
In detail, The Domain Name System; is that the phonebook of the web. Humans access information online through domain names, like dnskart.com or nameken.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can recognize easily and load Internet resources.
Each device connected to the web features a unique IP address that other machines use to seek out the device. DNS servers remove the necessity for humans to memorize IP addresses like 192.168.1.2 (in IPv4), or more complex newer alphanumeric IP addresses like 2500:cd00:2038:1:: c529:c7a4 (in IPv6).

How does DNS work?
The process of DNS resolution involves converting a hostname (such as www.dnskart.com ) into a computer-friendly IP address (such as 192.168.1.2). An IP address is given to every device on the web, which addresses is important to seek out the acceptable Internet device — sort of an address is employed to seek out a specific home. When a user wants to load a webpage, a translation must occur between what a user types into their browser (dnskart.com) and therefore the machine-friendly address necessary to locate the dnskart.com webpage.
In order to know the method behind the DNS resolution, it’s important to find out about the various hardware components a DNS query must pass between. For the online browser, the DNS lookup occurs “behind the scenes” and needs no interaction from the user’s computer aside from the initial request.
There are 4 kinds of DNS servers involved in loading a webpage:
• DNS recursor — The recursor are often thought of as a librarian who is asked to travel find a specific book somewhere during a library. The DNS recursor may be a server designed to receive queries from client machines through applications like web browsers. Typically the recursor is then liable for making additional requests so as to satisfy the client’s DNS query.
• Root nameserver — the basis server is that the initiative in translating (resolving) human-readable host names into IP addresses. It is often thought of like an index during a library that points to different racks of books — typically it is a regard to other more specific locations.
• TLD nameserver — the highest level domain server (TLD) is often thought of as a selected rack of books during a library. This nameserver is that the next step within the look for a selected IP address, and it hosts the last portion of a hostname (For dnskart.com, the TLD server is “com”).
- Authoritative nameserver — This final nameserver is often thought of as a dictionary on a rack of books, during which a selected name is often translated into its definition. The authoritative nameserver is that the last stop within the nameserver query. If the authoritative name server has access to the requested record, it’ll return the IP address for the requested hostname back to the DNS Recursor (the librarian) that made the initial request.
