IP reputation definition
IP reputation refers to the credibility score assigned to an internet protocol (IP) address based on past activities. It’s integral to various cybersecurity mechanisms used to combat spam, fraud, and cyberattacks. An IP address with a good reputation is less likely to be flagged by security systems, while one with a poor reputation can be blocked or restricted.

- Web security: Websites might block or restrict access to IP addresses with a poor reputation to protect against attacks or fraudulent activities.
Pros and cons of IP reputation
