# 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
