In this video we will guide you from the basics to a deeper understanding of DNS, how it works?
We’ll start with a simple introduction to DNS, covering its history, how it translates domain names into IP addresses, and how it differs from the DNS host file.

𝑾𝒉𝒂𝒕 𝒊𝒔 𝑫𝑵𝑺? – Understand the core concept, like the phonebook of the internet. It translates human-readable domain names (like www.itechnets.com) into IP addresses (like 192.x.x.x), which computers use to identify each other on the network.

𝑯𝒊𝒔𝒕𝒐𝒓𝒚 𝒐𝒇 𝑫𝑵𝑺 – Traces back to the early days of the internet. How DNS evolved into what it is today.

𝘿𝙉𝙎 𝙃𝙤𝙨𝙩 𝙁𝙞𝙡𝙚 – The DNS host file is a simple text file used by your operating system to map hostnames to IP addresses. It acts as a local DNS resolver, allowing your computer to quickly translate domain names into IP addresses without querying a DNS server.

𝑯𝒐𝒘 𝑫𝑵𝑺 𝑹𝒆𝒔𝒐𝒍𝒗𝒆𝒔 𝑰𝑷𝒔 – DNS resolves IP addresses by querying a series of servers—from local cache to root servers and authoritative servers—until it finds the corresponding IP for the requested domain name.
