🔍 Your Web Browser is Dumb….without DNS🔍
Did you know your web browser is clueless when it comes to finding websites? When you type in a URL like academy.networkchuck.com, your browser has no idea where to go. That's where DNS, the Domain Name System, steps in to save the day! 🌐

In this video, we dive deep into the magic behind DNS. We'll break down how your browser queries DNS servers to turn website names into IP addresses, making the internet work seamlessly. From how DNS can be hacked to how you can secure your own DNS with tools like SecureDNS from TwinGate, we've got it all covered. 💻

My favorite topic DNS, remember "it's Always DNS"

[keithrbumgarner]

You’re right “there is no spoon”, only sporks.

[alsothejiraguy]

It's not DNS.
There's no way it's DNS.
It was DNS.

[Milhouz]

How am I supposed to eat my cereal when "there is no spoon"!

[Blaxolot]

"You are awesome! You just queried a TXT record and found this secret message! Take a sip of coffee and give yourself a pat on the back. Post this in the comments to let people know you found it: \"there is no spoon\""

[TinugaGamage]

the editor on this video is insane 😂😂😂

[FisheySauce]

0:25 Most people couldn't dial a rotary even with the number so there's that too.

[Bunnys]

Very good summary of most of the important parts. Some time ago I actually read through the whole RFC as I implemented my own DNS server from scratch in C# :D It currently runs on my raspberry pi with mono.

ps: SOA stands for Start Of Authority, not "State" :) Other than that all pretty accurate and comprehensive.

pps: fun fact: in german "acid" is called "Säure" and DNA (Deoxyribonucleic acid) is actually called "DNS" in german (Desoxyribonukleinsäure). I think that's pretty fitting, the DNA of the internet :)

The secret message is: "You are awesome! You just queried a TXT record and found this secret message! Take a sip of coffee and give yourself a pat on the back. Post this in the comments to let people know you found it: \"there is no spoon\" " Love your videos, Chuck, keep up the great work.

[nhchiu]

Wait, usually DNS makes my internet NOT work 😂

[hassanfazeel]

Also, please teach how to prevent DNS servers from getting hacked in upcoming videos.

"Your browser is kind of dumb"
I couldn't agree more (I am forced to use Edge on this borrowed PC)

[Kurplix]

Just finished my cup of coffee. Now I'm ready for this video!

[ruhnsyfrvr]

This fits nice and snug into your CCNA playlist. Appreciate the content!

[ickteqp]

This was fun, I know dns but still liked it. It's been a while since I've seen any of your videos. I still remember before you went YT full time. You've done so well. Keep it up!

[Seedlinux]

One of the best DNS video explanation I have seen. Kudos.

[jimshapedcoding]

I was looking into your videos from 4 years ago, and today, the editing and the quality of the metaphors to simplify your explanations is second to none, thanks for inspiring how instruction should be done.

[curtijam]

Great video! Clear, concise, and fun. Love the content.

[raffiepro]

even back then most people didn't really remember any phone numbers apart from their own, they used phone books (or whatever they were called)
