DNSSEC is typically managed by the DNS service provider or Registrar that hosts and manages your domain name's DNS records.

If your DNS provider supports DNSSEC, they can assist in generating and maintaining the required DNSSEC records. Domain name registrants may also manage DNSSEC themselves if they operate and manage their own DNS infrastructure.

Please contact your DNS service provider or Registrar to confirm whether DNSSEC is supported and how it can be enabled for your domain name.
