The official client library for ipify: A Simple IP Address API.

GitHub License GitHub Stars GoDoc Build Status



ipify is the best IP address lookup service on the internet. It's fast, simple, scalable, open source, and well-funded (by me!).

In short: if you need a way to pragmatically get your public IP address, ipify is the best possible choice!

This library will retrieve your public IP address from ipify's API service, and return it as a string. It can't get any simpler than that.

This library also has some other nice features you might care about:

  • If a request fails for any reason, it is re-attempted 3 times using an exponential backoff algorithm for maximum effectiveness.
  • This library handles errors properly, and usage examples below show you how to deal with errors in a foolproof way.
  • This library only makes API requests over HTTPS.


To install ipify, simply run:

$ go get

This will install the latest version of the library automatically.


Using this library is very simple. Here's a simple example:

package main

import (

func main() {
    ip, err := ipify.GetIp()
    if err != nil {
        fmt.Println("Couldn't get my IP address:", err)
    } else {
        fmt.Println("My IP address is:", ip)

Now, in regards to error handling, there are several ways this can fail:

  • The ipify service is down (not likely), or:
  • Your machine is unable to get the request to ipify because of a network error of some sort (DNS, no internet, etc.).

The library will output an informative error message in the event anything fails.

One thing to keep in mind: regardless of how you decide to handle errors, the ipify library will retry any failed requests 3 times before ever failing -- so if you do need to handle errors, just remember that retry logic has already been attempted.
