Domain Name System

DNS stands for Domain Name System. Think of it like the internet's phonebook. It translates human-readable domain names (like google.com) into IP addresses (like 172.217.164.110) that computers use to identify each other on the network. Every website you visit, every email you send, relies on DNS to work behind the scenes.

When you type a domain name into your web browser, your computer needs to find the corresponding IP address to establish a connection with the server hosting that website. It does this by sending a DNS query to a DNS resolver, which acts as an intermediary between your computer and the DNS servers responsible for managing domain name records

dig Tool:

The dig tool is a command-line utility for querying DNS name servers. It provides detailed information about DNS records, including but not limited to A, AAAA, CNAME, MX, and TXT records. By using the dig tool, you can inspect DNS records and gather valuable information about domain configurations.

You can learn more about the dig command by entering man dig in your terminal

The Challenge

Your mission is to leverage your DNS querying skills and the dig tool to uncover the hidden flag within the TXT record of our domain, ctf.aayus.me. The flag has been cleverly concealed within the TXT record response, waiting for you to discover it.
