cf-ip

cf-ip is a tool designed to scan IP addresses and identify Cloudflare reverse proxy IPs.

Usage

To use finder, you need to specify the following required options:

Options:
  -asn int
        ASN (required)
  -n int
        Concurrency, default 10 (default 10)
  -s string
        Server name (required)
  -t_cf int
        CF proxy check timeout, default 3000(ms) (default 3000)
  -t_p int
        Port check timeout, default 500(ms) (default 500)

Example usage:

./finder -s example.com -asn 12345 -n 20 -t_cf 5000

This example command will scan the IP addresses associated with the server name "example.com" and the specified ASN 12345, using a concurrency level of 20. The timeout for CF proxy check is set to 5000 milliseconds.

Please note that the options -s and -asn are required, and you must provide values for both of them.

TODO

• Support configuration file
• Enable log output
• Support custom IP addresses
• Implement network speed and latency testing
• Integrate with HAProxy

Contribution

I’m a beginner in Golang and I’m still learning how to code better. I invite experienced developers to join me in improving cf-ip. I would appreciate any pull requests, feedback, or guidance from you.
