Everything You Need to Know About DNS: Crash Course System Design #4

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.

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?

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!

A valuable content, can you explain CIDR as the similiar method?

Amazing videos! What library/tool are you using to make the videos? Pleeease, share.

I have seen your works from the beginning, I appreciate your hard work, thank you for making this to be more understandable.

Is it possible to modify the DNS records in local cache of system.

This is one of the best explanations of how DNS works I have seen in a while. Thanks so much 😊🙏

I love the way you explain things you think you can do a playlist on dynamic programming ? Related to getting a job on an approach to solve leetcode or hackerank questions I think it may help us uk people apply for jobs thanks again!

Can you explain DNS in email role. I can't under it

Why would a network be connected to a FC00 dns server and not have a number instead

I am surprised that there was no mention of ICANN in the video. Where does ICANN stand in the DNS resolution? Are you referring to ICANN as Root resolver here?

Amazing 👏 Short enough to keep my attention and low level enough to be interesting and informative

Great video, I appreciate the free content and I'm looking forward for more!

hard to understand this diction, though. sorry to say! cause the content is ok.

If DNS uses UDP as the transport protocol, how does the DNS resolver correlate a given UDP request for a DNS query to any of the downstream servers to a given response? My understanding is UDP doesn’t have responses like TCP, so how do you get this “request/response” behavior?

I'll just stick to /etc/hosts - an OG DNS

DNS translate domain names to IP addresses. It's hierarchical and de-centralized.

awesome!

Great video!

Didn't know that you could shorten TTL before changing DNS records to ease the transition.
Very valuable information, thank you!

I love this channel!

Thanks for the Info, man
