Nginx - Check your public IP

Sometimes you just need your public IP, and nothing more. A simple config change in nginx can offer you exactly this.

Add the following location segment to the server segment of your choice. You could replace /ip with another term.

location /ip { default_type text/plain; return 200 $remote_addr;}

Now, if you visit the destination of the server segment with the subdirectory /ip, you'll find your IP. Try it out and visit https://itt.sh/ip.

The neat part is that it works well in the CLI too:
curl itt.sh/ip
wget -qO- itt.sh/ip
Powershell
Invoke-RestMethod itt.sh/ip or irm itt.sh/ip

Depending on your setup, some tweaking is necessary in regards to TLS, redirects, and so on.
