Ever wondered how your devices get an IP address automatically or how typing
Let’s uncover the two networking heroes behind the scenes - DHCP and DNS.
➡ Uses Ports 67 & 68 and the lightning-fast UDP protocol.
➡ Follows the DORA process: Discover → Offer → Request → Acknowledge.
💡 Without DHCP, you’d have to manually set IPs for every single device - imagine the headache in a large network! 😅
➡ Does the reverse too - Reverse Lookup maps IPs back to names.
➡ Runs on Port 53, using UDP for speed.
Think of DNS as the phonebook of the internet - it helps your browser find where a website “lives.” ☎️

https://www.google.com/ just works like magic? 🪄Let’s uncover the two networking heroes behind the scenes - DHCP and DNS.
DHCP (Dynamic Host Configuration Protocol)
➡ Automatically assigns IP addresses to connected devices.➡ Uses Ports 67 & 68 and the lightning-fast UDP protocol.
➡ Follows the DORA process: Discover → Offer → Request → Acknowledge.
💡 Without DHCP, you’d have to manually set IPs for every single device - imagine the headache in a large network! 😅
DNS (Domain Name System)
➡ Converts domain names (like google.com) into IP addresses - this is called Forward Lookup.➡ Does the reverse too - Reverse Lookup maps IPs back to names.
➡ Runs on Port 53, using UDP for speed.
Think of DNS as the phonebook of the internet - it helps your browser find where a website “lives.” ☎️
