ipdata is a free and open-source ip address lookup system. It combines the results retrieved from multiple maxminddb databases to provide you general geo/isp data for version 4 addresses. The project is currently available as a publicly consumable API, an easily importable Golang package called ipdata for use in your own Go projects, and a public Docker image on DockerHub.

Please note: The hosted version of ipdata.info does not store ANY ip data that is requested. If this is a real security concern of yours I recommend either using the self hosted Binary/Docker image or importing and utilizing the package yourself.

Features

The lookup system is extremely easy to understand and includes only one output format (JSON). What is returned to you is outlined in the below sample response. If you decide to use the package yourself the response struct can be found here.

Getting Started

Public API Usage

Using the API is very simple. All that's needed to lookup an IP is to send a GET request using the below URL schema to our origin.

https://ipdata.info/lookup/{ip}

Installing

To start using IPData on your local system, install Go and run go get:

$ go get github.com/s32x/ipdata

This will install the ipdata binary on your machine.

Running with Docker

To start using IPData via Docker, install Docker and run docker run:

$ docker run -p 8080:8080 s32x/ipdata

This will retrieve the remote DockerHub image and start the service on port 8080.

Full Go Example

package main

import (
    "log"

    "github.com/s32x/ipdata/ipdata"
)

func main() {
    // Create the ipdata client
    ic, err := ipdata.NewClient()
    if err != nil {
        log.Fatal(err)
    }
    defer ic.Close()

    // Perform the lookup
    log.Println(ic.Lookup("172.217.6.110"))
}
