DNS queries per second
2,000 QPS per VPC
If the DNS queries per second exceeds the threshold, a risk of request rate limit will rise, and the availability (99.99%) stated in SLA will not be guaranteed.</td>
Recursive subdomain resolution
After the Recursive Subdomain Resolution feature of Private DNS is enabled, queries for a subdomain for which no records are set will be forwarded to the Public DNS. If this feature is not enabled, such queries cannot be properly resolved.
If you have set a CNAME record, the target IP of the CNAME record will be synchronously returned after the CNAME flattening feature is enabled. We recommend you enable the Recursive Subdomain Resolution feature before using this feature. Otherwise, no final result can be returned if the target IP of the CNAME record requires query in the Public DNS.
Number of Round-Robin DNS Records
Weight setting is unavailable for round-robin DNS of TXT records.
The PTR record does not support round-robin DNS.
