I am not certain, but since you say it is very urgent, feed the output of the node into a Debug node set to Show Complete Message and carefully inspect all the properties shown.

The source IP is in the `msg.req` but it is hard to find if you are not familiar with that object as it is typically too large to completely show in the debug sidebar. Look up the ExpressJS request object online for details and work through each element to get to the data.

I think you'll get the full contents if you add a function node and in it call

```auto
console.log(msg.req);

```

You'll see the output in Node-RED log (not in debug sidebar).

</div>

finally the answer is (msg.req.ip), however it did not appear in the console.log(msg.req). I found it in theExpressJS request object online.

I tried it myself and you are right. A lot of data is output but the ip is not there while it still works as `msg.req.ip`. Strange indeed. Thanks for the update.

I investigated this a bit and iterating the properties of `msg.req` using `for (const item in msg.req) {` does find `msg.req.ip`, however `msg.req.hasOwnProperty("ip")` returns false, which I assume means that `req` is derived from an object type that has this property. I guess that the debug output only shows OwnProperties of the object being shown.

The same way you found the IP, a quick internet search shows that the information in request can be retrieved also.

In a **function node** after your http in :

```auto
msg.remoteAddress = msg.req.connection.remoteAddress
msg.remotePort = msg.req.connection.remotePort
msg.localAddress = msg.req.connection.localAddress
msg.localPort = msg.req.connection.localPort
return msg;

```

use a **complete msg debug node** after the function to see the reply when a request is made.  
ps .. what is the need for that .. isnt that localPort assigned by the OS and may change everytime ?

After reading a little bit more about Node.js req.connection, I think its better to replace **connection** with **socket** because connection is deprecated and may be removed in future Node js updates.

```auto
msg.req.socket.localPort

```

req.socket has the same effect.
