: Getting IP address and location of my own server instead of visiting user's I have a MEAN Stack application deployed on a server and am using Nginx as proxy server to handle the request and

@Steve110

Here's the Nginx Conf which works for me, placed at the path /etc/nginx/conf.d/example.com.conf.

server {
listen 80;
listen [::]:80;
server_name example.com;

proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

location / {
proxy_pass "http://localhost:1234/";
}
}


No other Nginx Conf required, as of my previous implementation i was having another conf file at the /etc/nginx/sites-available/default directory which was conflicting as a Duplicate Server Name.
Lastly, i would like to add that use Nginx Testing command before resetting the changes. Which was a huge help. Command: nginx -t.

And in Node.js, this is the most appropriate way to access Client's IP Address.

var getClientAddress = (req.headers['x-forwarded-for'] || '').split(',')[0]
|| req.connection.remoteAddress;
console.log(getClientAddress);


Cheers ;-)

Because your main application server is behind a proxy server, you will naturally be seeing the IP address of the proxy server, since this is effectively the "client" making the request to your application server.

You need the IP address of the client that makes the request to the proxy server - the originating IP address. The only way to get this information is if the proxy server passes on the IP address that made the request. Proxy servers commonly do this with the X-Forwarded-For HTTP request header.

X-Forwarded-For: <client-ip-address>


However, this header can contain multiple IP addresses (comma separated) if multiple proxy servers have been passed through:

X-Forwarded-For: <client-ip-address>, <previous-proxy-ip>
