Currently, we can only add a whitelist/allowlist IP address ranges which makes it very very hard to just block a specific country or a list of IP addresses.

The main use case for this is blocking a list of IP Address ranges that are harmful such as if our application is under a DDOS attack or other forms of brute force attacks.

This is really important to improve the application security and prevent DDOS attacks which in this day and age is very likely for any web/mobile application that has any noticeable traction.

Services such as Azure already provide such features so it is surprising that MongoDB Atlas doesn't already support this!
