Abour RRL and Best Practise

[Onur GURSOY]

Hello Everyone,

Bind9 is a good product and benchmark.
It has good documentation especially about vulnerabilities.
I wonder one thing, nowadays,

For brute force, reflection, ampliciation and etc. attacks, there is
prevention which is name response rate limit (RRL).
Question:
What is the default value rate-limit ?
What is the best practise, best value for rate-limit clause .

Thanks in advance.
Have nice day and healthy day,
With best regards
