When it comes to our online activities, there are many behind-the-scenes components that contribute to our overall experience. One such component is the Domain Name System (DNS), which plays a crucial role in translating domain names into IP addresses that computers can understand. But does changing DNS affect anything? In this article, we will delve into the world of DNS, explore its functions, and discuss the potential impacts of changing your DNS settings.
Introduction to DNS
The Domain Name System (DNS) is a global network of databases that stores information about domain names and their corresponding IP addresses. It acts as a phonebook for the internet, allowing users to access websites and online services using easy-to-remember domain names instead of difficult-to-remember IP addresses. When you enter a URL into your web browser, your computer sends a request to a DNS server to look up the IP address associated with that domain name. The DNS server then responds with the IP address, and your computer uses this information to connect to the website.
How DNS Works
The process of DNS resolution involves several steps. First, your computer sends a request to a recursive DNS server, which is usually provided by your internet service provider (ISP) or operating system. The recursive DNS server then queries a root DNS server to find the IP address of the domain name. The root DNS server responds with the IP address of a top-level domain (TLD) server, which is responsible for managing the domain name. The recursive DNS server then queries the TLD server to find the IP address of the domain name, and the TLD server responds with the IP address of the domain name.
Types of DNS Servers
There are several types of DNS servers, each with its own role in the DNS resolution process. These include:
Recursive DNS servers, which are responsible for resolving domain names on behalf of clients.
Authoritative DNS servers, which are responsible for storing information about domain names and their corresponding IP addresses.
Root DNS servers, which are responsible for directing recursive DNS servers to the correct TLD server.
TLD servers, which are responsible for managing domain names and their corresponding IP addresses.

What is DNS and how does it work?
The Domain Name System (DNS) is a critical component of the internet infrastructure that translates human-readable domain names into IP addresses that computers can understand. When you enter a website’s URL into your browser, your device sends a request to a DNS server to resolve the domain name into an IP address. The DNS server then responds with the corresponding IP address, allowing your device to connect to the website’s server and load the requested content. This process happens quickly, usually in a matter of milliseconds, and is essential for navigating the internet.
The DNS system is a distributed database that consists of a network of DNS servers, each of which stores a cache of domain name mappings. When you change your DNS settings, you are essentially telling your device to use a different DNS server to resolve domain names. This can be done for various reasons, such as to improve internet speed, enhance security, or bypass geo-restrictions. Changing your DNS settings can have both positive and negative effects on your online experience, depending on the DNS server you choose and your specific needs.
