The way you explained is excellent. Great Job Sir.
Well explained – On point
Excellent Explaination…loved it.
This is one of the most pretty 😍 explanation … really thank you 😊
What is preferred to use as a DNS server? Iterative or recursive and why?
Very clearly. Thank you sir
This is not in depth. This is more like an overly verbose introduction to DNS.
You lost me. LOL
Amazing explanation, this is the way i learn the best
Wow – what a great explanation. Thanks!
Wish I would have come across this a few years ago. Anyways its never too late. A very great video. Subscribed.
Wow. He got it. Explain it on live examples and everyone gets it. Thank you!
What if my primary dns server is shut down….will its query be resolved by an alternate dns server?
And what if both goes down.
We have two 2008r2 dcs . We are going to demote them,keeping the dns service. Both this dcs are primary and alternate dns servers to clients
Brilliant, Smooth, Intuitive and to the point.

Thank you for great presentation. Excellent.

Excellent explaination! 🤝✌️
Correction, putting entries in the host file does NOT input it in any cache.
DNS is always (by default on linux/windows/mac) queried 2nd, the first query will always check your host file first. You can modify the order of lookups on linux by flipping the order within the /etc/nsswitch.conf file, not sure about doing this on windows but it maybe possible in the registry somewhere.
iirc, this is not an iterative query, ISP dns server(dc01 in your video) is a recursive server, that always manages all requests by himself and collects answers. Servers like root, and tld would either forward you or send an error. That is called iterative. Correct me if im wrong
Very clear and perfect explanation of DNS. Thank You…
I would say outstanding technical presentation and thanks for this
amazing ground-up tutorial, kudos <3
give your courses on udemy
Great & helpful video, surely my exam will be easier after this.
I thought dns was just for websites
I just discovered you! Great explanations!
What OS are you using? Windows Server? Trying to figure out how to get to DNS Manager screen.
explained really well. i think i finally get how it works. thanks
Awesome explanation, thank you! One question, I hear of SOA is that like going to the root DNS and the root DNS updates all other DNS Servers with the new IP’s when users request a specific IP? does that make sense?
This is the best tutorial…. Cheers!!
service, not system.
Very understandable speech. Thank you. You made me understand what my teachers failed to.
Superb ….. very clear fundamentals …. excellent
Thank you for not having a disturbing/distracting back music!
Thank you so incredibly much for taking the time to do this
Thanks. The last part about how Windows appends the DNS suffix is very useful to know.
