Understanding IP Blocking
IP blocking is a security technique that prevents visitors from specific IP addresses from accessing your website. It can be implemented at the individual IP level, for IP ranges (using CIDR notation), or for entire geographic regions.
IP blocking is commonly used to stop known bad actors, prevent fraud from high-risk regions, comply with geographic restrictions, or block automated attacks.
