dnsZoneId

The ID of the Azure DNS Zone which should be used for this Front Door Custom Domain. If you are using Azure to host your DNS domains, you must delegate the domain provider's domain name system (DNS) to an Azure DNS Zone. For more information, see Delegate a domain to Azure DNS. Otherwise, if you're using your own domain provider to handle your DNS, you must validate the Front Door Custom Domain by creating the DNS TXT records manually.
