cPanel DNSOnly and DNSSEC

cPanel & WHM supports DNS Security Extensions (DNSSEC) in DNS clusters. A DNS resolver will compare the DNS server’s DNSSEC record to the DS record at the registrar. If they match, the record is valid.

• You can create, manage, or delete a domain’s DNSSEC keys in cPanel’s Zone Editor interface (cPanel » Home » Domains » Zone Editor).
• The system uses the /usr/local/cpanel/scripts/dnssec-cluster-keys script to synchronize and revoke currently-active DNSSEC keys in a DNS cluster. If you wish to perform this step manually, run that script as the root user.

For more information about DNSSEC in cPanel & WHM, read our DNSSEC documentation.
