What is IP Reputation?

How is IP Reputation related to Blocklist (Denylist)?
IP Reputation and Blocklist (Denylist) are both key concepts in threat intelligence. A blocklist is a list of IPs, domains, URLs, or file hashes known to be malicious. Firewalls, DNS resolvers, and email gateways use blocklists to automatically block traffic from known bad actors. Blocklists must be kept current to remain effective.
