IP Range Matcher
Automatically extract IP ranges (CIDR) from arbitrary text (logs, configs, docs, etc.) and verify if the target IP is included.
Common Use Cases
Security Log Analysis
Extract IP ranges from firewall/Nginx logs to verify if a suspicious IP belongs to a known whitelist (e.g., VPN, CDN).
Cloud Provider Verification
Paste massive IP range JSONs from AWS/Cloudflare to check if an IP belongs to their infrastructure.
Log Deduplication & Extraction
Paste messy server logs or any text to automatically extract and deduplicate all IPv4/IPv6 addresses for further analysis.
Network Troubleshooting
Quickly find which rule matches a specific IP from complex router configs or ACL lists.
