What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A shell script that attempts to bypass web application firewalls (like Cloudflare, Incapsula, SUCURI) by finding the origin server IP through historical DNS A records. It checks whether old IPs still respond for the domain and outputs a confidence level based on HTML response similarity.
Use cases
- find the origin IP behind Cloudflare
- bypass WAF for bug bounty testing
- discover old unmaintained servers still responding for a domain
- check if a firewall can be circumvented via DNS history
- locate subdomains pointing to the origin server
When to choose
- you are a bug bounty hunter testing WAF-protected targets
- you need a quick shell-based tool with no heavy dependencies
- you want to check historical DNS A records for origin IP leaks
When to avoid
- you need a full-featured reconnaissance framework
- you require Windows support
- you need an actively developed tool with frequent updates
