Helper library that checks if a given IP belongs to known CDN ranges (akamai, cloudflare, incapsula and sucuri).
The library can be used by importing github.com/projectdiscovery/cdncheck. here follows a basic example:
package main
import (
"log"
"net"
"github.com/projectdiscovery/cdncheck"
)
func main() {
// uses projectdiscovery endpoint with cached data to avoid ip ban
// Use cdncheck.New() if you want to scrape each endpoint (don't do it too often or your ip can be blocked)
client, err := cdncheck.NewWithCache()
if err != nil {
log.Fatal(err)
}
if found, err := client.Check(net.ParseIP("173.245.48.12")); found && err == nil {
log.Println("ip is part of cdn")
}
}
