If you're too young, and don't know what a phone book is, it's like DNS for phones numbers

[devsauce]

There is something special about buying your first domain name and pointing it to your website

I teach at a university and I'm playing this when I get to the DNS section of my lecture!

[victorsaisse]

Do I know how DNS works? YES.
Am I going to watch how it works? YES!

[anupamdahal]

I have learnt a lot of new things that I have never worked with from your videos, like AWS, nginx, kubernetes, graphQL(and other dbs), typescript to name a few. One thing that I don't understand is how they work together. I would really love to see a video where you design a mock system using all of these (and possibly more) and explain each of their roles and why you chose it (kinda like your reverse-cloud migration video using raspberry pi).

Whenever I think of a software architecture I think of them as several layers that interact with each other. However, I am unable to assign which layer what belongs to by watching a stand alone tutorial about a single tool.

 Btw, I am a college senior pursuing CS major and I love your content. Thanks for all the awesome contents.

Meanwhile, 2 days ago, I get asked about the DNS resolution flow on an interview, I mean fireship is really on point 🔥

[etiennebruines]

DNSSEC in 100 seconds would be interesting as well

[jujijiju]

I know the DNS protocol pretty well. But I'm still gonna watch it for the quality.

Your video editing and information presentation skills are just insane.

I'd love a "beyond 100 seconds", where you deepdive into how the system actually works and explain topics like DoH/T

[yogevboaronben-har]

Hey Jeff, thnx for the awesome videos!
A "100 seconds of event-loop" video would be very cool 😎

[boboertyusa]

Great video for people who have previously learned computer networking but need a refresher on certain parts.

Great video.
I just want to mention that there are also iterative resolvers where the resolver gets other dns servers from the one he is trying to resolve the dns record and then asks those other dns servers.

[alemalohe]

One thing I've learned from this channel, if not everything, is that I can do anything.

[StuartLoria]

More dev ops please. This server stuff needs to be demystified.

[devcodesforever]

Will share this with my computer teacher 😎

[garymurphy]

nice and concise and to the point as usual

[Dawa]

Always High Quality Videos Fireship... Thanks. Commenting so the algorithm blesses you sir

[melekRebai]

This dude is like a superhero but for tech, I've never seen in my 10 years of experience someone who can simplify and explain complicated stuff in 100 seconds like this

[nokkhtrobosu]

Man man 😭😭😭...I was searching for this a long time 😭😭💗💗 thanks

[azeezlukman]

Great video, thanks.
It's better ended with more short and informative video.
