Is this recursive lookup or iterative lookup ? DNS uses TCP or UDP port 53 or both ? Excellent and to the point video especially single one page diagram which gives 10,000/- feet birds view ...
Thank you. Where is DNS resolver located? And also the rest of other servers?
Thank You ❤
Thanks for sharing.

I have a question that comes to mind We assume that we have 5 records, all of them with the same domain name, and each record has a different IP Why when requesting query The Name Serverin Response brings me all five records, not one or two Is this constant in dns? Or there something that can control this? I mean two records only go not the five
Very nicely explained

Why don't we directly go to authoritative server .... When we know that the information is not available at the first two place

Very first this process is too quick . And second every server on internet reads the Top level domain(.dev)then second level domain (the cloud girl)and in last sub domain .
This is flawless:))

I really like this video the comparison, and the use of the transparent drawing board is ingenious. However I have a question; does the DNS resolver return the IP address directly back to your home router? or does the IP back to your ISP and then to your router? I had it in my head that all of your internet traffic went PC > Router > ISP > Internet > ISP > Router > PC If anyone has a good link as to how the traffic is sent & received plz share, Thanks

Yes, it does if it has the IP address otherwise it sends the request further and then replies back

Thank you Priyanka, can we get a video on different DNS record types and how to use each?

Thanks for the feedback. I will work on it.
Quick Question: Your diagram shows two-way communication between the resolver and each successive lookup server. I thought that each successive lookup server goes immediately to the next server in line until the record is found and only then returns an answer to the resolver. Can you please clarify this for me? Best
@pvergadia

Yes, your understanding is accurate. The reason I show two way arrows is that it wont go to the next lookup if it find the answer, in which case it will go back to the user without recursion from any of those intermediate steps. Hope this helps.
Your explanation is nice and simple. Thank you
my DNS got crossed can anyone help

Great to hear that you would like to see more fundamentals! I am working on a playlist.
If one directly enteres the host's IP address, followed by the resource path (e.g.: 123.459.77.93/about), will the request still undergo DNS resolution process?
Thank you
