whatcdn

Whatcdn is a tool that tries to detect if an IP/domain/URL uses a CDN or Cloud.

• This tool only makes use of simple HTTP/DNS (A,CNAME,PTR) requests and CIDR lists as its detection method.
• This repository is mainly a laboratory to implement and give suggestions to https://github.com/projectdiscovery/cdncheck
• "I've read the code and have concluded that you're a noob. It is the shittiest program ever. Sorry. - http://1u.ms/"

Heavily inspired by:

• https://github.com/projectdiscovery/cdncheck
• https://github.com/99designs/clouddetect

Install

go install github.com/brenocss/whatcdn@latest

Usage
