PR Feedback

💡 General suggestions: The PR is well-structured and addresses the issue of IP duplication effectively. The use of hashing to create unique identifiers for each rule and policy reference is a good approach. However, it would be beneficial to handle the error returned by the hash function in a more informative way, rather than just ignoring it.

🤖 Code feedback:

suggestion	Handle the error returned by the hash function. Currently, if the hash function returns an error, it is ignored. It would be better to log the error or handle it in a way that would not silently fail the operation. [important]
relevant line	'+ if ruleHash, err := hash(rule); err == nil {'

suggestion	Consider using a more descriptive name for the variable 's' in the hash function. Variable names should be descriptive and convey the purpose of the variable. [medium]
