In this scenario you can’t use Azure Private DNS Zones since you can’t access them from the internet. The last scenario is if your default route points to the on-premises and all traffic is routed to the internet from there (the legacy way). with Active Directory) and internet gateway forced in on-premises On-premises and/or cloud workloads with own DNS servers (e.g. Remember always use the public facing name for applications to reach the resource. Use your local ISP DNS as a forwarder for other DNS queries.DNS server responds the private IP to client.DNS Server forwards the request with conditional forwarder to Azure DNS that asks it from Azure’s public DNS servers and the DNS servers responses the private IP to the client.VM asks the public name .net from local DNS server.You can use for example couple of domain controllers in cloud to act as a DNS relay. Remember to put forwarders also for Azure DNS server to point Azure’s public DNS services in IP 168.63.129.16. ) and point those towards your Azure VM which is a DNS relay in cloud. After you have the relay server, just create a conditional forwarder to on-premises DNS for your public DNS-zones (e.g. Without some server that acts as a DNS relay in the VNet, your DNS traffic is not routed to the internet (and Private DNS Zone) from Azure. To get the name resolving working, install DNS servers also to the cloud. In this scenario you have your own DNS Servers such as a Windows Server Active Directory integrated DNS that you want to use for name resolving. When you create a private endpoint, you can have an automatic DNS record creation to your Private DNS zone and it works. You have same benefits when having a full name resolution on Azure services. You can route some of your internal networks to the internet from some other point (for example from on-premises datacenter), it really doesn’t matter. So if you have a route to the internet available on Azure you can also use Private DNS zones. with Active Directory) and multiple internet routes You access storage account with a public IP provided by Azure.Private DNS Zone Answers to request through Azure DNS.Private endpoint in Azure public DNS service If the request to the public DNS-name (.net) is coming from VNet the Private DNS Zone answers the private endpoint’s internal IP, but if the request is coming from internet, the Azure’s own DNS answers the public IP. When creating the private endpoint, just select the dedicated zone for automatic DNS registration and all configured. Just create a Private DNS Zone to Azure named by domain name that is going to be the private endpoint domain name for your resource for example .net. This is the most straight forward scenario. with Active Directory) and internet gateway forced in on-premisesĪzure VNET without custom DNS Servers (without Active Directory) On-premises and/or cloud workloads with own DNS servers (e.g.Azure VNET without custom DNS Servers (without Active Directory).Normally you have three options depending of your infrastructure: There are several ways to achieve the name resolution, but I will now tell how I would implement it. Sounds nice? YES! Name resolution options Also when you are deleting the private endpoint, the A-record is removed automatically when using Azure Private DNS Zones. Azure engineer does not need to have access to your DNS-infrastructure e.g. When creating a private endpoint, you can tell also to automatically add the A-record to the private DNS zone. You can create required private link DNS zone e.g. I have a storage account called bloggerzstorage and it has a public IP address provided by Azure.ĭNS queries allowed from Virtual Network not from Internet When you create a private endpoint (the resource that is used in the Private Link -concept), you will change the public name resolution for the resource towards you are creating the private endpoint. When implementing Azure Private Link, remember always use the public facing name for applications to reach the resource. I’ve seen that this isn’t so clear for everyone how private endpoints works so I’d like to clarify it little bit more. Then you need some DNS-configurations and everything works like a magic. It uses resource called private endpoint to accomplish it. In short, Azure Private Link connects your PaaS service such as SQL Server, Storage account or App Service to your subnet and gets a private IP for it. it got it General Available (GA) status and after that there have been added many PaaS-services for it. Azure Private Link has been available in Azure little bit over year now.
