We do not support DNSSEC. This means we do not provide an option to configure DS records in our DNS service. However, if you have already added your domain to our platform, then you will need to disable DNSSEC at your domain registrar in order for the domain to receive DNS requests.

If you require DNSSEC functionality on your domain, we recommend switching to a different DNS provider for DNS management. With this approach, you can continue to manage your Rcs.iss and other services through the Rcs.is Control Panel while entrusting your domain management elsewhere. We recommend Cloudflare as they support DNSSEC.
