DNS Hosting Platform Using PowerDNS

The sdnog DNS-control platform is designed for high availability and reliability of DNS zones. It consists of a hidden master DNS server and two publicly visible secondary DNS servers, all running PowerDNS. This structure ensures secure DNS management and effective load distribution
