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.
