thx, saved me a bunch of time. I was just curious why my host game me the option to set my own nameservers, and the more i dug into it, the more confused i got. Now it makes a lot more sence. Thanks again
Perfect video but I can't still understand how resource records works and which servers have them. Also, a little clarification: isn't it an iterative query? Still thx a lot man, ^^
It's awesome.... Good work. Please post how tcp, udp, icmp protocols are working.... When ping coomands are used to connect to another computer which protocol makes this process easier. Pz share
chandni Mahajan , it can be up to 48 hours on an isp name server or only 15 minutes on a host server. This helped me: support.managed.com/kb/a604/dns-propagation-and-why-it-takes-so-long-explained.aspx
I don't understand why we need dot root server? in this case why ISP recursive request directly go to .com DNS sever. What is benefit of dot root server when it doesn't know anything
So look at .com .net .gov .info .biz .mil you name it, the list keeps growing, keeping it all under one big group is not very efficient; this topology of having different layers surprisingly optimizes the way caching and searching works by splitting the massive amount of ever growing list of domains. Imagine each one as a forest, in which you have trees, in which you search for individual leaves. .com is its own forest Now to answer your question... You you can have rajiv.com and rajiv.info and rajiv.net So if you have everything into the same “forest” you add one more layer of complexity because now you need to determine are you searching for .gov? com? Instead of eliminating that problem by simply filtering by .com Comparing costs time.
One of the best DNS videos I've ever seen. Great work!

simple and clear . Great video
the best video on DNS on youtube! short, simple and complete
Thanks so much for the visuals. A lot of other videos have flashy videos but your drew the graph and that's what I needed to see.
Very well done. Great layered approach. Excellent!
This is great! I'm taking a course and didn't understand and now I do. Thanks
Thanks for the fantastic explanation. Much appreciated.
Thank you for this video. Really broke it down well!
Amazing explanation, I now clearly understand what dns and dns lookup is. Thank you for uploading this
Agreed one of the best explanations here!
clear and concise explanation. the best video on dns i found.
this is really helpful, please cover all the networking concepts in detail in video series. thanks
excellent video and visuals
Your video is referenced in my computer science class :D
This is great.Simply explained the process.Thank you very much.
This was a well done video
Loved the explanation :)
Great explanation
Excellent! Very useful! Thx
Great job!!!!!!!!
Excellent explanation - thank you. Very clear. I love a good diagram. :-)
Good video. Thank!
Great video. Thnaks. Why do we need to create reverse lookup zone ?
Great explanation! I have a question though.
Say yahoo has a primary DNS server and a secondary DNS server. Which server’s IP address does com send?
beautifully explained...lovely
Thanks alot
Perfect video but I can't still understand how resource records works and which servers have them.
Also, a little clarification: isn't it an iterative query?
Still thx a lot man, ^^
Thank you ! very informative video.
You explain easy way thank you for share
Thanks for easy and intuitive explanation :)
Will there be another videos of the series "How DNS works"? Reverse DNS?
Nice explanation !!
Amazing
You rock man 👍👍
great vedio
How does the ISP know the address of the root level nameserver?
Great video thank you
It's awesome.... Good work. Please post how tcp, udp, icmp protocols are working.... When ping coomands are used to connect to another computer which protocol makes this process easier. Pz share
Thanks for the video. Just wanted to double check. I thought that it's Authoritative query once it's passed the ISP DNS server?
Simple. Thanku
Really helped. Thanks
Nice video! Thanks
Good Job! Nice Video
do the other dns servers cache the new name as well?
Thanks for sharing this video. I have quick question . how long chache remain on DNS server?
chandni Mahajan , it can be up to 48 hours on an isp name server or only 15 minutes on a host server. This helped me: support.managed.com/kb/a604/dns-propagation-and-why-it-takes-so-long-explained.aspx
Where do the registrars fit into this process?
nice thank you very much ! :D
Does anyone know the name of the background song? It's actually very calming lol
Great video thank you, for other searchers audio track is entitled Nice and Easy by Hoang Gia Vinh
Thanks
nice video .. but annoying music
I don't understand why we need dot root server? in this case why ISP recursive request directly go to .com DNS sever. What is benefit of dot root server when it doesn't know anything
Imagine dot as index page...with contents and subcontent..
@@khanolkarsagar but we already know we need to go com subcategory, then why going to dot require?
So look at .com .net .gov .info .biz .mil you name it, the list keeps growing, keeping it all under one big group is not very efficient; this topology of having different layers surprisingly optimizes the way caching and searching works by splitting the massive amount of ever growing list of domains.
Imagine each one as a forest, in which you have trees, in which you search for individual leaves.
.com is its own forest
Now to answer your question...
You you can have rajiv.com and rajiv.info and rajiv.net
So if you have everything into the same “forest” you add one more layer of complexity because now you need to determine are you searching for .gov? com? Instead of eliminating that problem by simply filtering by .com
Comparing costs time.
guess i need to setup a reverse lookup🤷🏻♂️😮💨
video is great the but the music is really distracting
.com server already knows NS for yahoo.com , then y again query to yahoo.com ?
It's not authorative for same, hence request is forwarded
what no broken indian english? holy... this is something else
You, I like you :D
@@CasaRolThen ask he/she maybe he also likes you?
Maybe worth to try
great video, thanks for sharing!
thanks
