Get the IP address from request url

Question

How to get the IP address from HTTP request url or the client IP from where my node code is running.

http://127.0.0.1:1000/samp/

The client IP can be an nginx IP or public IP. Any help on this will be really helpful.
Thanks.

What have you tried so far?

One second, you want the **client IP**, or the **current machine IP**? — The Scrum Meister, Nov 28 '13 at 06:06
@The Scrum Meister I need the client IP. I used request.connection.remoteAddress and request.headers['X-Forwarded-For'], but Im not getting the exact IP. — user87267867, Nov 28 '13 at 07:50
Is it possible to get the IP from the request url using connect? — user87267867, Nov 28 '13 at 08:07

Assuming you want the client ip, you'll need to first decide if you trust "X-Forwarded-For" headers (that is: you are behind a reverse proxy that you yourself set up and which you trust, or you trust the proxies along the way).

If so, then get the ip in req.headers['x-forwarded-for'] (this could potentially be a list).

If not, then req.connection.remoteAddress is the answer.

Im using connect. I tried req.ip which is returning me output undefined – user87267867 Nov 28 '13 at 07:55
req.ip is only in express. Use what I wrote above. – Nitzan Shaked Nov 28 '13 at 08:13
How can I get the nginx ip if my code is running behind reverse proxy? – user87267867 Nov 28 '13 at 12:49
Modern Nginx gives you a slightly different `Forwarded` header. See https://www.nginx.com/resources/wiki/start/topics/examples/forwarded/ – Qix - MONICA WAS MISTREATED Aug 28 '20 at 01:00

Try this

app.get('/', function(req, res) {
      res.send(req.connection.remoteAddress);
    });
