Public DNS zones hold the trusted DNS records that will reside on OCIs nameservers. You can create public zones with publicly available domain names reachable on internet. You need to register with a DNS registrar.

Private DNS zones contain domain names that resolve DNS queries for private IP addresses within a VCN. You can create private zones to define your own domain name for private address resolution. You can also combine VCNs for private DNS resolution over several VCNs.
