@@NetworkDirection this video is amazing 🎩 Last week i had an exam on network sevices and since the documentation that was provided by our teacher is poorly made I had to do my own research on DHCP, DNS, NIS, NFS, AD, SMTP/POP/IMAP & SNMP. And u just resumed my hours of research in 13 minute, u covered all wat I learned and more. I hope that ur channel reaches more people in the near future. Many thanks for ur efforts 😊.
Why don,t you allow community contributions to subtitle it? These videos are amazing, but not everybody understands English, and I could help to translate them into Spanish.
That's a great idea. I hadn't really thought about it before. I've enabled community contributions on this video. I'll look at enabling it on more in future. Thanks for this!
@Network Direction Using root hints and find the IP address is an iterative query per video? But video description/summary says recursive? Or Am I missing something? The alternative is to use root hints, where the server asks other servers for hints about where the authoritative DNS server is located. It does this using recursive queries
Rather than trying to explain it, I would like to suggest this blog article from the ancient times (2009): blogs.msmvps.com/acefekay/2009/11/12/dns-recursive-queries-vs-iterative-queries/ That might help explain it differently
@@NetworkDirection Thanks for the blog link. So it is relative to what client of a DNS server is asking for. Doesn't matter if DNS server is using root hints to find resolved IP Address or it is taking another DNS server's help.
@@MsPgouru Sounds like you'll be a DNS expert before you know it! Another thing you could try is setting up a lab DNS server, and looking at the queries in wireshark
Hi, great tutorials! I have a question: at 12:33, why is it looking for the answer in a ".COM" DNS server if the domain it's ultimately looking for is a ".NET" domain ?

Every single video so far, is an amazing job! Thanks for your great work!
Thanks George!
This is one of the best Network Tutor resource I have come across, kudos!
As always amazingly simplified explanation. Love your videos !!!
This is amazing. Far better than google networking course on coursera
👍
wow I've read a lot about and never found such a perfect and easy explanation. Good job!
why am i so late on this channel :( , just wow!!
you earned a subscriber
Thanks 😀
Thank you for this great intruduction. Will be great if you can make another more advanced content on DNS!
Maybe in the future I can do that. I've got to finish this series before getting too side tracked though ;)
I have probabilities exam tomorrow. But I have to stop preparing and watch this lol.
😄 Don't get too distracted!

it's looking for blog.cloudflare.com, with is a .com space
@@NetworkDirection Ah, I see, I mistook the server name at the top left to the url you're searching. Thank you for the quick reply!

Thanks!
Do we have link for dns configuration in linux .. ?
I haven't created a link for this myself, but you could try this one out: linuxconfig.org/linux-dns-server-bind-configuration
