Generating an NSEC Record |
| 摘要 |
A DNS server receives, from a client device, a DNS query for a resource record type at a domain name. The DNS server determines that the resource record type does not exist at the domain name and generates an answer that indicates that the queried resource record type does not exist at the domain name and also indicates that a plurality of other resource record types exist at the domain name regardless of whether those plurality of other resource record types actually exist at the domain name. The DNS server transmits the generated answer to the client device. |
