  • Cloud DNS private zones require that you use the Google Cloud metadata server for name resolution. Its responding metadata server is 169.254.169.254. Is this what you are looking for? https://cloud.google.com/dns/docs/troubleshooting#query-dns-name-using-metadata-server:~:text=Cloud%20DNS%20private%20zones%20require%20that%20you%20use%20the%20metadata%20server%20for%20name%20resolution. – James S Nov 22 '22 at 00:45

Cloud DNS Private zones require that you use the metadata server for name resolution. Compute Engine instances receive internal DNS resolution information as part of their DHCP leases. By default, the instance's metadata server (169.254.169.254) resolves internal DNS names. If you change the name server configuration for your instance, you cannot resolve records in Compute Engine internal DNS (the .internal zone) or in Cloud DNS managed private zones, forwarding zones, and peering zones unless your replacement DNS server forwards these queries to 169.254.169.254.
