GoCDN-Scanner

GoCDN-Scanner is a tool in Go for network auditing. It automates subdomain discovery and CDN provider detection (Cloudflare, Akamai, AWS Cloudfront, Fastly) through concurrent CIDR range analysis using goroutines. It runs as a single binary with zero dependencies.

What it does

• Enumerates subdomains using multiple passive sources
• Detects CDN provider for each subdomain (Cloudflare, Akamai, AWS Cloudfront, Google, Fastly, Sucuri, BunnyCDN)
• No active requests to the target — fully passive
