Creating a Public DNS Zone

Create a public domain name service (DNS) zone to hold the trusted DNS records that reside on Oracle Cloud Infrastructure's nameservers.

You can create primary public zones with publicly available domain names reachable on the internet. For more information, see Public DNS.

You can also create a secondary zone, which pulls records for the zone from an external primary server.
  • The OCI DNS service is limited to 1000 zones per account and 25,000 records per zone. Customers with zone and record size needs exceeding these values are encouraged to contact support at support.oracle.com.

  • Zone file uploads are limited to 1 megabyte (MB) in size per zone file. If a zone file is larger than 1 MB, you need to split the zone file into smaller batches to upload all the zone information. For more information and a workaround for this limitation, see Zone File Limitations and Considerations.

  • Public DNS zones are only supported in the OC1 commercial realm. For more information and to check if a region is included in OC1, see Regions and Availability Domains.
