ifconf

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

Usage

Just the business, please:

$ curl ifconfig.uk
127.0.0.1

$ http ifconfig.uk
127.0.0.1

$ wget -qO- ifconfig.uk
127.0.0.1

$ fetch -qo- http://ifconfig.uk
127.0.0.1

Country and city lookup:

$ http ifconfig.uk/country
United Kingdom

$ http ifconfig.uk/city
London

As JSON:

$ http --json ifconfig.uk
{
  "city": "London",
  "country": "United Kingdom",
  "ip": "127.0.0.1",
  "ip_decimal": 2130706433
}

Features
