# ipd

[![Build Status](https://travis-ci.org/mpolden/ipd.svg)](https://travis-ci.org/mpolden/ipd)

A simple service for looking up your IP address. This is the code that powers
https://ifconfig.co

## Usage

Just the business, please:

```
$ curl ifconfig.co
127.0.0.1

$ http ifconfig.co
127.0.0.1

$ wget -qO- ifconfig.co
127.0.0.1

$ fetch -qo- http://ifconfig.co
127.0.0.1
```

Country and city lookup:

```
$ http ifconfig.co/country
Elbonia

$ http ifconfig.co/city
Bornyasherk
```

As JSON:

```
$ http --json ifconfig.co
{
  "city": "Bornyasherk",
  "country": "Elbonia",
  "ip": "127.0.0.1",
  "ip_decimal": 2130706433
}
```

## Features

* Easy to remember domain name
* Supports HTTPS
* Open source under the [BSD 3-Clause license](https://opensource.org/licenses/BSD-3-Clause)
* Fast
* Supports typical CLI tools (`curl`, `httpie`, `wget` and `fetch`)
* JSON output (optional)
* Country and city lookup through the MaxMind GeoIP database

## Why?

* To scratch an itch
* An excuse to use Go for something
* Faster than ifconfig.me

## Building

Compiling requires the [Golang compiler](https://golang.org/) to be installed.
This application can be installed by using `go get`:

`go get github.com/mpolden/ipd`
