In the video, I delved into how DNS works, from converting human-readable domain names like google.com to IP addresses, to the role of authoritative name servers and the DNS resolver in the resolution process. Exploring the complexities of DNS architecture, I highlighted the decentralized nature of DNS and the crucial role of root name servers in directing requests. Emphasizing the step-by-step resolution process, I illustrated how browsers connect to servers through DNS resolution. Stay tuned for upcoming videos on building a DNS server.

Great stuff !!! Waiting for the upcoming videos
Man! You're amazing. You deserve all the appreciation in the world
Thank you for making it easy.
loved it, thanks arpit. just exceptional
Thank you so much!
wow great stuff
Wow eye opener
Amazing Content Arpit. Looking forward for your next video on creating a DNS server.
Wow! Never knew that much of stuff was happening internally. Thank you Arpit for making such videos.
This is Dope. 🔥
Great explaination as always. One more addition to this video could be hosted zone delegation (explicitely) for better managing hosted zones ...
superb
Amazing
I leave every else video side, whenever youtube recommends your conceptual videos, love to spend time here, atleast I get something out of it, Great work Arpit :-)
Thank you Varun :) it means a ton.
💛
Your videos really help me with my work. Can you also make a video on SSL certificates and cryptography?
sir can you please make video on internals of docker
Make a video on cdn and cloudfront
Arpit, can you please throw some light on how to handle database deployments at scale?
If there are too many objects being deployed, how to make sure that the deployments don't fail.
Also are there any ways to have a no downtime deployment?
There are different deployment strategies to make zero downtime deployment. For example, Please check rolling restart and blue-green deployment
Does your anycast video mentions anything about BGP protocol? Was expecting to learn about bgp in this video.
Why would you expect BGP should be covered in a DNS video.
By the way, my LB video skims through anycast and BGP but given the complexity, I have not covered BGP entirely, yet.
Can malicious websites not brodcast legitimate server's IP address with anycast?
Is it possible to get away with IP address ? Instead we can directly use "unqiue url" to find the right server ? Browsing will be much faster if there is no need to find IP and thereby reducing overall traffic. what IP address can do but not possible with "unique url" ?
I love your content. I urge you to use noise cancellation on your microphone because we can hear the traffic and people sounding horns.
I am using Blue Yeti, supposedly the best. I have tweaked some settings, hopefully it works better the next time.
@@AsliEngineeringi honestly think you’re a great teacher so that’s why I’m suggesting the improvement in noise quality. Maybe you can also look into sound proofing your room with foam insulation. Your room is quite evidently prone to echoing so I think the horn sounds are easily bounced around and going into your microphone. Sound proofing will help a lot with that.
Hey Arpit, I have subscribed to your newsletter. I watched your entire video, you have great knowledge but I was not able to get it. Try to make simple videos with simple diagrams, you wrote a lot of things but did not go through it. It may be my understanding capabilities but I just gave an honesh feedback.
There are lots of nuances that needed to be covered. Simple video would not do justice to the concept.
I would highly recommend build an ability to read and watch dense stuff. Because that is where you build the right intuition.
@@AsliEngineering Thanks Arpit, I'll build this habit.
dns is a recursive process in itself? am i correct arpit
Yes. It is a recursive process generally done by DNS Resolver/Recursor. This Resolver is generally provided by your Internet Service Provider(ISP) or you can configure to use a third party Resolver server such as CloudFlare's.
So that means, all the TLDs will have all the authoritative Name servers record in the world. If a company or service provider wants to configure their own Auth N Server, it will register a public IP for that and register it in all the TLDs?
Nice question & I also had the similar doubt...next I am having assumption that if it is what it is then it should be a cluster of TLDs holding the IPs of all NS. And next assumption is that sometimes I feel few moments lag in loading the site page & that can be due to either these many hopes to identify the actual IP or the server of that website is slow

Arpit i think you deleted my yesterday's comment about the DNS article. Not sure why would you do that.
I have not even read the comments. I have not deleted anything. Feel free to post it again.
@@AsliEngineering see, again I posted the same comment to your reply and it doesn't show up here...
TH-cam comments have spam filter
@@akshay__sood TH-cam must be flagging it off due to some reason. I did not even get a notification about it.
@@rahulpalve401 I ain't spamming. It was just a regular reply.
