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.

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

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

[vadud]

Really enjoy your youtube articles. Would you cover the difference between recursive and iterative dns query may be on another youtube episode. Thank you!

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

[non-tech-comment] I have been watching contents from this channel for very long. Always felt like he had a familiar face. Today, I just realised he had a striking resemblance with the Keymaker in matrix, (he is a more happier version😄) 🔑❤

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?
