Understanding DNS in Azure 

Love this explanation. Thank you John for being thorough and not cutting corners.

This is excellent John, exactly what I needed to fill gaps in a Udemy course for an exam

Probably the clearest DNS-related video I’ve ever seen. Thank you!!

I'm only 5 minutes into this, but had to stop and give a thumbs up. Thank you for putting this out there. So far, it's super clear and is answering some of my questions. I'm on old-fashioned IT consultant trying to learning about Azure networking.

your explanation is so simple it is in the point where a vegetable can understand the concept, thanks

This was a brilliant walk-through. I learned a lot. I must have watched it before because I had that "red" line under the video. Today I was ready to absorb it. That's the wonderful thing about your video series, I can return as many times as necessary until I "learn" the material.

Great explanation of Azure DNS. I really appreciate the white board, instead of just Power Point slides.

You're the best, I'm not tired to say it each time I see your videos, your knowledge of Azure Infrastructure is Amazing :)

Thanks a lot John, Very thorough explanation on Azure DNS. I really like the way you explain things. It is easy to understand and remember.

Great SO far. Only 4 mins into the lecture. You never fail with providing a clean and concise explanation of an Azure topic. Felt rusty and not confident after going through the DNS topic on the Microsoft learn for az-104. Knew I would gain a better understanding of DNS once I landed here. Thanks again!

So awesome. Now i finally understood why a DNS resolver is needed when i want to access a DNS zone which is hosted in Azure DNS in hybrid scenarios.

The most underrated channel. He suppose to have millions subscriber

Studying for the Administrator exam, these videos are a lifesaver! Thanks again!

DNS is always abroad topic to understand for me. It really helps me to understand deeply. Thank you, John.

Thanks John. Yours is always the best and detailed explanation that is easier to understand.

Great Work John , its really appreciated if you link each option with a real use case , as you mentioned for Private links . basically no one like to have a custom DNS with management overhead ,

Nice, bite-sized video on Azure DNS. And glad to hear you're a Top Trumps fan, John - didn't think you were old enough to remember that card game!

Amazing to know how Azure DNS works. Thank you, John, so much for such a great explanation.

Finally I can see light at the end of the tunnel. Thanks !!

So, as always, you nailed it. I would really say that John Savill is not only at least my SOA for Azure Knowledge. Maybe the video is a few days older; it's fundamental for every PaaS / IaaS Guy out there. Thank you so much!

Brilliant! Just brilliant. Thank you for explaining it in ways which are so easy to understand.

Thank you for your time and good explanation.

Succint and friendly overview. Thanks a mil for sharing this, John!

Best Azure teacher on youtube. Thank you very much

Thank you John, awesome, as usually :) Your videos are now my main source of knowledge of Azure :) There are several questions left unanswered related to the private endpoint & DNS stuff: 1. In the private endpoint I can add "DNS Configuration" - what that does and what it is needed for is completely unclear. Private zones just work. They just need a record(s), so why do we need "DNS Configuration"? What it creates, and how it affects DNS resolution? 2. In the portal, when you create a private endpoint and want DNS integration, you cannot pick just a "random" private zone. It must have some specific name. So, what are these names needed for and how they work. I noticed that even if they are private, they can be resolved from the public internet. So it's sort of magic that needs some explanation.

Again, many thanks. Contimually learning more about the world of Azure. About to do az-900 . Who said can't teach old dogs new stuff. Cheers

Great video, John. Please keep producing them...

On a scale of 1-10, this video is a 12, thank you John.

Awesome, I love the way that you explain on Whiteboard. It make more sense to me

Thanks mate, it's very detailed and easy to follow as I build my Azure Cloud foundation.

The best lecture on DNS In Azure wow!!!

Should of touched on apex domain support using azure public dns. It's a hidden gem. Great video

Best Man with Best DNS Lecture!!

Very informative and fun to watch at the same time

Thanks for this John, you covered the Private-Link resolution which I was struggling with 😀

The best Channel. I found it very useful.

Fantastic info John! Really wish you had a whiteboard download for this video as DNS is a complex matter to explain verbally :D

It is so adorable the way you tech sir 🤩 big fan

Awesome. Keep it up John

Very nicely explained. TY John!

Thank you very much! It helps me to understand how it works! I appreciate it!

man finally i understand this. thank you so much!

Thank you for taking my request :) , this is amazing and exactly what I needed . Appreciate it .

Bodybuilder from IT. Great sir

As usual a perfect video, thanks a lot for sharing 👍

Great stuff, as always!

Great insight to internal DNS in Azure!

Great job explaining DNS, John. Thanks!

You are amazing.Thank you for explaining the concepts so clearly.

John: If this is useful, please like, comment, subscribe and share. Me: * does all the above first and then watches the video because I know this video is going to be super helpful *

Just stumbled on your content. Very excellent work. I have subscibed, liked and now commented ;) Great work on your videos. Great cadence and explanations.

Great video, thanks ! At the end of the video, you mentioned Azure Traffic Manager - have you ever considered adding a video about differences between Azure Application Gateway, Azure Load Balancer,, Azure Traffic Manager, and Azure Front Door ?

Very well explained. 😄

Thank you John, excellent content

Well rendered mate! I am hitting subscribe straight away!

Cracking content as always John!

Great walkthrough, thank you!

thank you John, this content is so valuable

Superb as always John!

Nicely done John, keep up the good work. I learned new things today = good day :-)

Excellent tutorial. Thanks!

Excellent Explanation Sir 🙏

Amazing video!!

Great video! SUGGESTION: Consider a lapel mike rather than directional - every time you turn toward the whiteboard your audio lowers.

Great content!

Amazing, very useful video.

Great video!!

If you have a azure private dns zone yourself for let's say sql databases and you want to connect to database in another tenant (supplier) which is using a private endpoint for the database, but also allows public access, it will not resolve. Because azure dns server will return the cname privatelink and then dns will go and check your own private dns zone. A workaround is to add a record in your private dns zone and point it to the location specific dns cname of the database.

Thanks for the explanation. I have subscribed as well.

Great work as always.

One word. Awesome!

Thanks for great vedio

Great video, I'd like you to breakdown auto registration and name resolution as some of us are pretty new

wow! now i know what recursive , conditional and forwarders are, all in under 5 min as appose to reading MS 100page document ..Thanks John as always u rock! .. . one question any video's on dns delegation for priv zone?

GREAT!!

Merciiii beaucoup.. you are the best 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

Thanks for the video. Just to make sure I'm understanding... Imagine I have an on-premises network with 80 Windows 10 clients and 20 HP printers, no DNS sever, a DHCP server in the firewall and a site-to-site VPN to Azure. I want to add DNS for the on-premises LAN using Azure IaaS. The best way to do this so the on-premises devices will get auto-registered in DNS is to create a VM in Azure that runs DNS. The on-premises devices and the firewall will use the VPN to auto-register and resolve the on-premises zone. I'll set up the firewall to use split-DNS to send public DNS requests to a public DNS server while requests for the on-premises zone go the VM in Azure. Is that right, or is there a way to avoid running the DNS on the Azure VM?

Great job!

Thanks for the video, subscribed as well. Question: what hardware are you using here for MS Whiteboard? Just a normal TV with a touchscreen layer over it?

If a customer has a landing zone with VPN to on-prem. There is a domain controller in Azure VM. VNET has custom DNS pointing to the on prem DNS. If the VPN goes down, do the Azure VMs still communicate? what is the correct architecture for this?

Hi John, thanks a lot for your videos, it is great and advanced content which really helps. One question, if one zone is public and private at the same time, will it go for the records of public zone in case it doesn't exist in private zone? Or if private exist it is only authoritative, for the answer, and won't go public? Thanks in advance

Excellent.

You Rock!! Thank you so much

Hi John Thank you for the great explanation. Quick question, I need to implement Hybrid DNS -On Premise to Azure. We have Gateway VPN connection, I learn I need to add a forwarder, so my question is the DNS request form my OnPremise DNS into Forwarder are going through Internet? Or through VPN connection to Azure? Thank you.

I have a VNET configured with custom DNS servers. Those DNS servers are for my AADDS instance. I also have those two VNETs peered. When I create a point to site VPN to connect to the first VNET, I lose DNS name resolution from my PC. Is there a way to configure my VPN or VNET peerings so I can be connected to the VPN and also use my corporate DNS servers for resolution on my PC? Also.. fantastic video.

Thank you excellent explanation, which white board and technology do you use?

Thanks for the video. Imagine I have added DNS entry on both at vnet & nic level..A virtual machine will look for which one? VNET or NIC

Thanks John, I really appreciate the high qulity content. I just have a question for my case. So a communications company will be the middle connection between my company's Azure infrastructure and our IoT devices deployed everywhere. We set up an S2S VPN connection with them to receive the traffic from the IoT devieces. I am just wondering, would the devices be able to send their DNS requests to Azure DNS (168.63.129.16) since they are connected via VPN, or should I set up a custom DNS server on a VM to forward their queries? Hope you will be able to read this, thank you very much :))))

I am using custom dns. I can't seem to resolve any external/lnternet dns queries (can't access internet) unless I have 168.63.129.16 as a forwarder in my custom dns server. Is there any way I use any public dns to forward my external queries and not azure dns??

What is that monitor you are using look great

you are an excellent teacher, do you have a course in Udemy?

Hi John, if a VM is not in any registration VNet, can it resolve other VMs that are in some registration VNet(s)?

Can the private DNS zone name in azure be same as the on-prem DNS zone name?

Are those private DNS zones VNETs?
