Understand the Basics of DNS
Before diving into the technical details of hacking a DNS server address, it is important to understand the basics of DNS. DNS, or Domain Name System, is essentially a phonebook of the internet. It translates human-readable domain names into IP addresses that computers can understand.
Every website has a unique IP address, which is essentially its physical location on the internet. However, remembering IP addresses for every website we want to visit is practically impossible. That’s where DNS comes in handy. DNS allows us to use memorable domain names instead of complicated IP addresses to access websites.
When you type a domain name into your web browser, it sends a request to a DNS server to translate that domain name into its corresponding IP address. The DNS server then sends the IP address back to your computer, allowing your browser to connect to the website.
DNS servers are essentially the backbone of the internet, making it possible for us to easily access the vast amount of information available online. Understanding the basics of DNS is crucial to understanding how it can be hacked and how you can protect yourself from such attacks.
What is DNS?
DNS stands for Domain Name System.
It is a hierarchical decentralized naming system that converts domain names into IP addresses and vice versa.
It is like the phone book of the internet that helps us remember website names instead of numerical IP addresses.
When a user enters a website address in their browser, the browser sends a request to the DNS server to resolve the domain name to an IP address.
The DNS server then responds with the IP address associated with that domain name, allowing the browser to connect to the correct server and display the website.
Without DNS, we would have to memorize numerical IP addresses for every website we want to visit.
Understanding how DNS works is critical to hacking it. Let’s take a closer look.
How Does DNS Work?
DNS translates domain names to IP addresses. When you enter a website’s domain name in your browser, the DNS server translates the domain name into an IP address that your computer can understand. This process is called name resolution.
DNS uses a hierarchical structure. DNS servers are arranged in a hierarchical structure that starts with the root servers. There are 13 root servers worldwide, and they contain information about the top-level domain names (TLDs) like .com, .org, .net, etc. The TLD servers contain information about the second-level domain names, and so on.
DNS caching improves performance. Once your computer has obtained the IP address for a domain name, it caches the information for a specified period. This reduces the number of requests made to the DNS server and improves performance. The cached information is used the next time you visit the same website.
DNS queries use UDP. When your computer sends a DNS query to a DNS server, it uses User Datagram Protocol (UDP). This is because UDP is faster than TCP, and DNS queries are typically small and require a quick response.
