An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing. A blacklist is a list of items that are considered undesirable or dangerous. In the context of IP addresses, a blacklist is a list of IP addresses that have been identified as being associated with malicious activity, such as spam, phishing, or hacking.
IP blacklists are used by a variety of organizations, including email providers, website hosting providers, and network security companies. By blocking traffic from blacklisted IP addresses, these organizations can help to protect their users from malicious activity. IP blacklists are an important tool for maintaining the security and integrity of the Internet.
