Blacklisting IP addresses, commonly known as IP blacklisting, is a cybersecurity measure that involves adding IP addresses to a blacklist to prevent access to specific online resources, such as websites, email servers, or applications. This practice is widely used to combat malicious activities, including spam, phishing, distributed denial-of-service (DDoS) attacks, and other forms of cyber threats.
Blacklisting IP addresses provides several critical benefits. It helps protect networks and systems from security breaches, prevents unauthorized access to sensitive data, and reduces the risk of malware infections and other cyberattacks. By blocking malicious actors, blacklisting IP addresses contributes to maintaining the integrity and security of online environments.
