From 83468619ff59e99a880bd2f45e493f8ec94d5bd4 Mon Sep 17 00:00:00 2001 From: marco370 <48531002-marco370@users.noreply.replit.com> Date: Wed, 26 Nov 2025 09:54:57 +0000 Subject: [PATCH] Add full CIDR support for IP address matching in lists Updates IP address handling to include CIDR notation for more comprehensive network range matching, enhances database schema with INET/CIDR types, and refactors logic for accurate IP detection and whitelisting.
