What Are the Restrictions on Concurrent Private DNS Requests?

To ensure the lookup efficiency of private domain names, only 2,000 queries are allowed on a single source IP address per second. If a server initiates DNS queries with an overwhelmingly high frequency, significantly in excess of normal service demands, and there are more than 2,000 queries per second, additional queries will not be processed.

If your services initiate an enormous volume of concurrent requests, enable DNS caching to improve lookup efficiency.
