Before enabling DNSSEC through MYNIC, ensure that the following requirements are met:
1. The domain name must use authoritative name servers that support DNSSEC.
2. The DNS zone must be signed with DNSSEC, including the generation of the required DNSKEY, RRSIG, and related DNSSEC records.
3. A valid DS (Delegation Signer) Record must be available on the authoritative name servers and retrievable by MYNIC.
4. The Administrative Contact or Technical Contact for the domain name must have access to the MYNIC Selfcare Portal to manage DNSSEC settings.
