How can I determine the IP address of a given request from within a controller? For example (in express):
app.post('/get/ip/address', function (req, res) {
// need access to IP address here
})
In your request
object there is a property called socket
, which is a net.Socket
object. The net.Socket
object has a property remoteAddress
, therefore you should be able to get the IP with this call:
request.socket.remoteAddress
(if your node version is below 13, use the deprecated now request.connection.remoteAddress
)
EDIT
As @juand points out in the comments, the correct method to get the remote IP, if the server is behind a proxy, is request.headers['x-forwarded-for']
EDIT 2
When using express
with Node.js:
If you set app.set('trust proxy', true)
, req.ip
will return the real IP address even if behind proxy. Check the documentation for further information
