IP2Tor allows to check if an IP address is a Tor exit node. This can be used to identify and block traffic from the Tor network. IPv4 and IPv6 addresses are supported.
It will run a daemon to download the Tor list from below sources and update it according to the time specified. It optionally uses a local file to cache the last results and allow continuous operation even after restart of your application.
Tor node lists:
It was observed that those lists only match about 72%, so they are both used as source by this package.
It is a Go package with no external dependencies. To download it:
go get -u github.com/IntelligenceX/ip2torThen use it like this:
package main
import (
"github.com/IntelligenceX/ip2tor"
)
func init() {
// Only download exit nodes, refetch the list every 2 hours.
// Cache it to the file "tor-ips.txt".
ip2tor.Init(1, time.Hour*2, "tor-ips.txt")
}
func main() {
ip := net.ParseIP("1.2.3.4")
ip2tor.IsTor(ip) // returns true or false
}
