Blocks or allows access based on IPs and CIDR ranges with admin IP protection and high-performance matching of the listed IP addresses
IP Blocker Pro is a powerful and flexible Joomla! system plugin that lets you control access to your website based on IP addresses and CIDR ranges (IPv4 and IPv6). It provides a high-performance and precise way to block unwanted visitors or restrict access to specific trusted IPs using efficient binary range matching.
The plugin stores IP ranges in a binary-safe format using a dedicated table, allowing fast and reliable range comparisons — even when dealing with thousands of entries. It also supports proxy-aware detection using standard headers such as X-Forwarded-For, ensuring accurate IP resolution even when your Joomla! site is behind a load balancer or CDN.
