+version: 1.0.0
+description: "Cloudflare IP ranges feed connector — pull the official Cloudflare edge IP ranges (IPv4 and/or IPv6) and emit normalized IOCs (CIDR + type) for import into the Threat Indicator Manager. Intended as an allowlist / known-infrastructure feed (mark benign in TIM). Free, no authentication required; stdlib-only, no extra Python dependencies."
+changelog: "1.0.0 — Initial release: fetch Cloudflare ips-v4 / ips-v6."
+category: feed
