Cloudflare's WAF utilizes IP ranges to detect and block malicious requests. It identifies patterns and signatures associated with common web attacks (SQL injection, cross-site scripting, etc.) and associates those patterns with specific IP addresses. If traffic originates from an IP range known to be associated with malicious activity, the WAF will block or rate-limit that traffic.
