linux dns server
I don't understand how does an operating system participate in domain name resolution except for providing "open()" and "socket()" system calls to open files and do network communication using sockets?
Fantastic!!!
Very nice video but can u tell me where dns resolver and dns server will be located???
thank you for your fantastic video! the audio and video information together was superb. thank you so much and i will highly recommend this video to others
Great video. What did you use to create the animation? Thank you in advance.
Awesome illustrations, keep it up 👍🏿
This is the best explanation on DNS I have seen. Thank you for such a presentation.
May i ask which tool you have used to make this animation, It's very impressive.
I literally got tears of joy by the end of the video. Do you know why? my brain realised it had a quality learning for 5:44 minutes. Hard to imagine the efforts behind making such a wonderful session.
Awesome explanation!!
Thanks for sharing.
best channel on system design
Thank you for explaining in a nutshell
What A Great Explanation, Wow
amazing!
why do not you intruduce the dnssec
can someone help me: does dns resolver run on my laptop or on a server?
Can you explain DNSSEC too?
Great! You should also cover different dns record types like a record, mx record, cname, Alias etc
Your skill for simplify things is not from this world. Thank you, I see you! 🙏
Very nice!
Thank you for your efforts.
What is the sotware that you use for editing the videos and how are you gathering different images and flowcharts of design?
Great video, very informative
4 quick questions….
1. Who owns the ip address of DNS resolver
2. Browser sends http request which is stateless, so every time it will go to check the dns resolver
3. How browser solves this quickly can you elaborate this much more.
4. Who will update the ip addresses of TLD name servers
can you do iptables next?
you make great videos
Amazing info, thanks. My concern is, there are a lot of request only for translate the domain to a ip address and after of that, the browser will can get the resources for that ip address. I know that there is running in a fraction of seconds, but is there a better way today instead to add in more dns server around the world? Regards.
You did not explain what exactly TTL is. Is it TTL of a DNS record, of a DNS cache entry, of a DNS request, of a DNS propagation event, … ?
I have a quick question. What is the logic to identify the country from the IP address.
The best
Perfect! Thank you!
