This plugin provides IP-based content restriction for sites built with WordPress. It is designed for administrators who need to make posts, pages, or other content visible only to visitors from specific network locations, such as internal intranets, staging environments, or partner portals.

CIDR Group Management: Create named groups containing lists of IPv4 or IPv6 CIDR ranges. Assign these groups to any post or page to control its visibility.

Strict Allowlist Model: A post is visible only if a visitor's IP address matches at least one CIDR range within an assigned group. Posts with no groups remain fully public.

Transparent Enforcement: Unauthorized visitors receive a standard 404 error, not a login prompt or access denial page, keeping restricted content invisible.

Broad Application: Restrictions apply consistently across the site, including singular views, listing queries, REST API responses, XML sitemaps, and feeds.

Trusted Proxy Support: Includes configuration for sites behind reverse proxies or CDNs to correctly resolve the original visitor IP address for accurate matching.
