How DNS works - DNS LOOKUP | DNS forward Look up explained STEP BY STEP with EXAMPLES | domain name
What does DNS Lookup mean?
A DNS lookup, in a general sense, is the process by which a DNS record is returned from a DNS server. This is like looking up a phone number in a phone book - that is why it is referred to as a "lookup". Interconnected computers, servers and smart phones need to know how to translate the email addresses and domain names people use into meaningful numerical addresses. A DNS lookup performs this function
The basic idea of DNS is that humans can't easily remember long strings of digits like machines can, but can much more easily remember words. So, when you type in a domain name like www.techopedia.com, the request is forwarded to a DNS server (whether locally or at an ISP), which returns the corresponding IP address. This address is then used by all the computers and routers to channel the request and responses of a user's session. The result is the user sees web pages as expected or has email show up in an in-box. The two types of DNS lookups are forward DNS lookups and reverse DNS lookups.
other terms related to DNS look are Forward DNS,Reverse DNS (rDNS),Domain Name System (DNS),DNS Server,Domain Name,DNS Record,Domain Name System Parking (DNS Parking)which are taken up in separate video tutorials.

One of the best DNS videos I've ever seen. Great work!

[@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

[@isaact4315]

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.

[@chloekimball536]

Really helped. Thanks

[@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?

[@dineshharmalkar4549]

Simple. Thanku

[@almazabraha]

Great video thank you

[@victord.4388]

Excellent! Very useful! Thx

Thanks

[@brianmisasa]

This was a well done video

[@priyankapati1144]

Loved the explanation :)

[@sonujalwal4768]

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

[@SajidAhmed94]

How does the ISP know the address of the root level nameserver?

[@syedarbaz3781]

Amazing

[@erikvasquez7827]

Great job!!!!!!!!

[@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

[@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, ^^

[@anaperel8590]

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?

[@connorflewitt8377]

Great video thank you, for other searchers audio track is entitled Nice and Easy by Hoang Gia Vinh

[@green10701]

Will there be another videos of the series "How DNS works"? Reverse DNS?

[@aisanh8258]

thanks

[@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?

[@FrankBugZappa]

do the other dns servers cache the new name as well?

[@arjunbhattacharya3623]

nice video .. but annoying music

[@jennymandl6910]

video is great the but the music is really distracting

[@JP-Gurley]

guess i need to setup a reverse lookup🤷🏻‍♂️😮‍💨

[@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

[@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.
