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!

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 ,

Amazing, very useful video.

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.

@NTFAQGuy

@@NTFAQGuy I did, several times, it didn't help to explain how "DNS Configuration" works. E.g. how public PaaS DNS name resolves to the private endpoint cname when requested from the VNET.

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

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 :))))

the 168.. only works ON the vnet. anything connected to it would NOT work as I talk about in the video. you would have to setup a DNS resolved on the vnet which could forward. Thanks for watching.

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.

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.

a VPN connection will normally inherit the DNS of the network you connect to which is required for accessing resources. Depending on VPN solution being used may be able to still hook into on-premises.

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?
