DNS Query Routing with Forwarders

DNS forwarders are used when a local DNS server cannot resolve a query itself. Instead of trying to find the answer on the internet, it forwards the request to another designated server. In a hybrid setup, you configure your on-premises Windows Server DNS to forward unresolved queries to an Azure DNS Private Resolver or to external DNS servers. To set this up, you first must ensure your Azure private DNS zone is correctly linked to your virtual network. You then configure the DNS settings on your virtual network, either using Azure's default settings or specifying custom DNS server IP addresses. Finally, you can create a test record in the private zone and use a tool like nslookup to verify that resolution is working through the forwarder.
