IP blacklist API allows you to configure a drop action that will stop forwarded traffic from a specific list of IP address or networks. This will protect your API from a wide range of online threats such as DDoS attacks.

IP address blacklisting is an essential tool in protecting APIs from a variety of threats and vulnerabilities, including DDoS attacks, distributed denial-of-service attacks (DDoS), and unauthorized access to critical data. However, the effectiveness of IP blacklisting depends on several factors, including securing APIs with Kong API Gateway and implementing proper security practices.

Understanding IP Blacklist API: What It Is and How It Works

The blacklist consists of reports from many sensors around the world that detect abnormal behaviour of Internet users, such as downloading and distributing copyright-violating content, sending spam or malicious traffic, or attacking other networks. These sensors collect data from Internet service providers and report this information to the blacklist, which is then accessed by organisations and individuals looking to strengthen their online security.

Some hackers and cybercriminals try to evade detection by using tools like VPNs or proxies. Others use command-line tools, which enable them to input software commands through text to avoid being impacted by automated blacklist checks. SEON’s software focuses on detecting and analyzing IP addresses to identify suspicious behavior.

The blacklist API endpoint can be configured to filter by country or by both the IP and port numbers, depending on your needs. You can also choose to limit the number of IPs returned with the maxAgeInDays parameter, as well as navigate the pagination via the perPage and page parameters. The generatedAt header contains a timestamp for the date and time that the report was generated, making it easy to identify freshness of the data.
