How can I get the public IP of the sender of a HTTP request ? NodeJS (express)

I'm trying to get the public IP of a HTTP request sender on a NodeJS server. I tried with: req.socket.remoteAddress req.connection.remoteAddress ...

But these lines gives me the local address of the server.

you can simply use req.ip in express, the docs https://expressjs.com/en/api.html#req.ip
