couldn't understand the concept after watching hours of videos he crystal cleared it in 6 minutes great video.

[@blackblather]

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

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?

[@aljodomo]

Your video is referenced in my computer science class :D

[@sonujalwal4768]

Great video. Thnaks. Why do we need to create reverse lookup zone ?

[@green10701]

Good video. Thank!

[@404unk]

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, ^^

[@crazyjipi]

You explain easy way thank you for share

[@NasirAli-hs8np]

Thank you ! very informative video.

[@itftcomputers]

Thanks for the video. Just wanted to double check. I thought that it's Authoritative query once it's passed the ISP DNS server?

[@The_memory_be_green]

Does anyone know the name of the background song? It's actually very calming lol

[@petrknetl5952]

Thanks for easy and intuitive explanation :)

[@hosamhamdy8230]

Thanks alot

[@RajivKumar-ee7xv]

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

[@khanolkarsagar]

Imagine dot as index page...with contents and subcontent..

[@RajivKumar-ee7xv]

@@khanolkarsagar but we already know we need to go com subcategory, then why going to dot require?

[@ashamaniq]

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.

[@chandnimahajan2791]

Thanks for sharing this video. I have quick question . how long chache remain on DNS server?

[@lydiarice3713]

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

[@lydiarice3713]

Where do the registrars fit into this process?

[@AlexandraCPacker]

Excellent explanation - thank you. Very clear. I love a good diagram. :-)

[@vimalarani8143]

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

[@MrBat000]

[@chandrasekharnadar9623]

.com server already knows NS for yahoo.com , then y again query to yahoo.com ?

[@khanolkarsagar]

It's not authorative for same, hence request is forwarded

[@syedarbaz3781]
