How to implement the storage of blocked ip addresses?

Question

Node.js

Hello, how can I implement the storage of blocked ip addresses? In radish, data is stored until the server is rebooted; in the database, it’s also not a very good idea to climb into the database with each request. What's the best way to implement?

Answer 1

store it in the database and cache it in radish. Write new ones right there and there.

Answer 2

You can keep the Bloom filter in memory and first check the possible ownership of the address, and only in the case of a positive result, climb into the database and check its actual presence. This is the case if there are much more requests from non-blocked addresses than from blocked ones (otherwise, such optimization would make no sense).
