What is DNS?

What is DNS?

DNS stands for Domain Name System. It is a fundamental technology that is used to convert human-readable domain names into machine-readable IP addresses. This system allows users to access websites by typing in a domain name, such as, instead of a long string of numbers representing the IP address. In simple terms, DNS is like the phonebook of the internet.

When a user types a domain name into their web browser, the request is sent to a DNS server to retrieve the corresponding IP address. A DNS server is a computer that contains a database of IP addresses and their corresponding domain names. It acts as a directory service, translating domain names into IP addresses.

The process of converting a domain name to an IP address involves several steps. First, the browser sends a request to the local DNS server, which is usually provided by the internet service provider (ISP). If the local server has the IP address for the requested domain name, it will be returned to the browser, and the website will load. However, if the IP address is not stored locally, the local server sends a query to the root DNS server.

The root DNS server is the starting point in the DNS hierarchy. It contains the IP addresses for the top-level domain names, such as .com, .org, .net, and country-specific extensions like .uk or .au. The root server then directs the local server to the DNS server responsible for the specific domain extension requested. This process continues recursively until the IP address is found and returned to the browser.

DNS plays a crucial role in the functioning of the internet and is essential for browsing the web. Without DNS, users would have to remember the IP addresses of all the websites they want to visit, instead of simply typing in the domain name. Moreover, it also ensures that websites are always accessible, even if their IP addresses change.

In addition to translating domain names into IP addresses, DNS also provides other features such as email routing and managing subdomains. It also enables website owners to make changes to their server’s IP address, without affecting its domain name.

In conclusion, DNS is a crucial technology that allows users to access the internet easily. It serves as a translator between human-readable domain names and machine-readable IP addresses, making it an integral part of the infrastructure of the internet.
