VMware Cloud on Public Cloud DNS forwarding services run in DNS zones, and enable workload VMs in the zone to resolve fully-qualified domain names to IP addresses.
Your SDDC includes default DNS zones for the Management Gateway and Compute Gateway. Each zone includes a preconfigured DNS service.
Important NSX Tier-1 gateways such as the Management Gateway and the Compute Gateway act as forwarders and relay the queries from VMs to the specified DNS servers. The devices also cache the responses to improve the performance.
Use the DNS Services tab on the DNS Services page to view or update properties of DNS services for the default zones. To create additional DNS zones or configure additional properties of DNS services in any zone, use the DNS Zones tab.
