Fallback to internet on Private DNS Zones: New feature which unblocks adoption of a fully managed solution for Network Isolation and simplifies scenarios with Private Link and Private DNS. This feature enables public recursion to occur in the event of receiving an authoritative NXDOMAIN response from Private DNS Zones. Customers can now rely on a fully managed native solution without using IaaS based DNS servers to unblock Private Link and Private DNS adoption. API, CLI and PowerShell are available today, with portal being available over the next 2 weeks.
What is fallback to internet on Private DNS Zones?
Fallback to internet in Azure Private DNS is a fully managed native solution. This property enables public recursion via Azure’s recursive resolver fleet when an authoritative NXDOMAIN response is received for a private link zone. This Resolution policy is enabled at the virtual network link level. In the Azure portal, this resolution policy property is enabled by selecting Enable fallback to internet in virtual network link configuration.
