-> Get public IP using [canihazip.com](http://canihazip.com/).
+### :warning: Deprecation notice
 
+The [canihazip.com](http://canihazip.com/) project stopped working. See the report at #2. As a fallback, this project is using [ipify.org](https://www.ipify.org/) with [patch 1.0.3](https://github.com/markogresak/canihazip/releases/tag/v1.0.3) so it does not break old usages.
+
+**For new projects, I suggest using [`public-ip`](https://www.npmjs.com/package/public-ip)**. It is better maintained, built to be more robust (to avoid issues like #2) and has a better feature set.
