Part 1: Theory 1. What is DNS (Domain Name System)? Definition: DNS works like the phonebook of the internet. It translates human-friendly web addresses into numbers that computers understand. IP Routing: Computers connect to each other using numerical addresses called IP addresses (e.g., 216.239.32.21 ). DNS routes users automatically so they do not need to memorize these numbers. Real-Life Example: Phonebook: Searching for "Sujan" gives you 9800000000 . DNS: Searching for mybrand.com.np gives the computer IP address 216.239.32.21 . 2. Main DNS Record Types Nameservers (NS): Tell the internet which server manages your DNS records. A Record (Address Record): Connects a domain directly to a numerical web server IP address. Example: Points mybrand.com.np \rightarrow 216.239.32.21 . CNAME Record (Canonical Name): Connects a domain or sub-domain to another domain name instead of an IP address. Example: Points [www.mybrand.com](https://...
