The Overview of DNS Leak
HI Hi, Greetings! 
Intimate February 
Today, I would like to share with you an article about the overview of DNS Leak. I hope this article has more support for Web and cloud engineers. Let's move to the article and I will explain the last part of this article.
PART 01:
What is a Domain Name System (DNS):
DNS (Domain Name System) is an internet technology that converts website addresses into code that computers can understand. This is critical for internet users to be able to access their favorite websites, search engines, social media, and streaming services.
The Domain Name System (DNS) converts a web address into an Internet Protocol (IP) address, allowing computers to recognize the location a user wishes to visit and allowing devices to communicate with one another. Web browsers employ DNS servers to get the IP address that users are looking for, allowing for a more user-friendly internet experience.
Users' DNS requests are forwarded to servers managed by their internet service provider (ISP), which keeps track of user information in logs. This can be a privacy issue because the data can be used by law enforcement agencies to track user activities, or sold to advertisers and other third parties without the user's permission in some countries. Users can circumvent this by using a virtual private network (VPN) to encrypt, private, and protect their internet activity.
All Domain Names and their accompanying IP Addresses are stored on a DNS server. When you type in a URL-
Your browser will make an IP Request (domain name) to the DNS Server (for example, www.zaheer.com)
The DNS Server will match the IP address associated with this URL and deliver your browser to the website.
The DNS system is necessary since the browser can only comprehend the numerical IP Address and cannot grasp the alphabetic URL.
What is a DNS Leak?
While requests are transmitted to an ISP's DNS servers, even when a VPN is being utilized to protect users, a DNS leak occurs. A VPN encrypts a user's internet connection, enclosing their communication in a private tunnel that conceals their whole browsing history. That means that everyone except the VPN provider can see the user's internet searches and website visits.
A DNS leak, on the other hand, occurs when the user's DNS requests leave the encrypted tunnel and are accessible to their ISP. As a result, everything they do online, including their IP address, location, and web searches, travels through their ISP, just like it would if they weren't using a VPN.
