 A simple service for looking up your IP address. This is the code that powers
-https://ifconfig.co.
+https://ip.level.io.
 
 ## Usage
 
 Just the business, please:
 
 ```
-$ curl ifconfig.co
+$ curl ip.level.io
 127.0.0.1
 
-$ http ifconfig.co
+$ http ip.level.io
 127.0.0.1
 
-$ wget -qO- ifconfig.co
+$ wget -qO- ip.level.io
 127.0.0.1
 
-$ fetch -qo- https://ifconfig.co
+$ fetch -qo- https://ip.level.io
 127.0.0.1
 
-$ bat -print=b ifconfig.co/ip
+$ bat -print=b ip.level.io/ip
 127.0.0.1
 ```
 
 Country and city lookup:
 
 ```
-$ curl ifconfig.co/country

-## Building
-
-Compiling requires the [Golang compiler](https://golang.org/) to be installed.
-This package can be installed with:
-
-`go install github.com/mpolden/echoip/...@latest`
-
-For more information on building a Go project, see the [official Go
-documentation](https://golang.org/doc/code.html).
-
-## Docker image
-
-A Docker image is available on [Docker
-Hub](https://hub.docker.com/r/mpolden/echoip), which can be downloaded with:
-
-`docker pull mpolden/echoip`
-
-## [GeoIP](https://www.maxmind.com/en/geoip2-databases)/[GeoLite](https://dev.maxmind.com/geoip/geolite2-free-geolocation-data?) Database (MaxMind)
-To utilise MaxMind [GeoIP](https://www.maxmind.com/en/geoip2-databases)/[GeoLite](https://dev.maxmind.com/geoip/geolite2-free-geolocation-data?) database to enhance the information provided to end users, you can download the relevant **binary** databases (`.mmdb` format) directly from MaxMind using the above links.
