Check which CDN providers an IP list belongs to

Description

This tool is based on the CIDR ranges collected by ProjectDiscovery in their cdncheck project. This is a cli implementation for easy use and it also contains a GitHub action to download everyday the json containing CIDRs.

Its main use case is to avoid port scanning and/or other intensive tasks on IPs hosted outside our target and that can also result in blocking or banning.

The tool reads from stdin the list of IPs and (by default) prints the IPs belonging to any CDN provider. Using the flags you can specify to print the ones that do not belong to CDNs or to print the detail of which provider it uses.

It detects the following CDNs: Azure, Cloudflare, Cloudfront, Fastly and Incapsula.

Install

go install -v github.com/six2dez/ipcdn@latest

• m (method):

  • cdn - prints only IPs on CDN ranges
