Go package to determine if an IP address resolves to one of the major cloud providers. Helpful for risk-scoring potential bot traffic in conjunction with other signals such as User Agent.
Currently the library consumes the published IP ranges from Amazon, Google, and Microsoft.
package main
import (
"fmt"
"os"
"github.com/99designs/clouddetect"
)
func main() {
ip := net.ParseIP("127.0.0.1")
if cloud, err := clouddetect.Resolve(ip); err == nil {
fmt.Println(cloud.ProviderName)
}
}
The default Client has an internal cache with a TTL of 12 hours. The first request to resolve an IP will be slow as it fetches all published ranges. See the clouddetect godocs for more detail on the API.
go get github.com/99designs/clouddetect/cli/clouddetect
then
clouddetect -ip=127.0.0.1
