Delegation Signer (DS)
A Delegation Signer (DS) record is a fundamental component of DNSSEC. It resides in the parent zone (e.g., at the Registrar/TLD level) and contains a hash of the child zone’s DNSKEY.
The DS record is what allows the “Chain of Trust” to work. When a resolver looks up your domain, it first checks the parent zone (.com) for a DS record. If found, it uses that record to verify that the DNSSEC keys provided by your domain’s name servers are authentic. Without a DS record at the registrar, your domain’s internal DNSSEC signatures cannot be validated by the rest of the world.
