Get IP address on client side with socket.io - node.js

Is it possible to get the client's ip address on clientside (within the browser) when using socket.io? Using pure Javascript alone can't get the client's IP address.

There is no way, unless you send the IP address over the socket from the server side.

How to get client's ipv6 address using node/express js?

I am using req.connection.remoteAddress to try to get the ip address from the client that do the request but I just get something like this ::ffff:10.1.86.195.

Any way to spoof original webrtc ip address?

Is there any way to spoof original WebRTC ip address on regular browsers like chrome, firefox and opera?
For example: I using some proxy and would like to spoof my WebRTC ip address same like proxy ip address. I don't need to disable it.
Running a TURN server is the best way. A TURN server acts as a proxy, you can can send and receive all your traffic through a remote host first.
You can then set iceTransportPolicy to relay in your RTCConfiguration. The PeerConnection will then only connect through that TURN server.

Node.JS socket io connection

How can I put the server IP address when I connect to the server in the frontend?
var socket = io.connect('http://localhost:3000/panel');
So instead localhost put the correspondent server IP address for the production environment.
Thanks.
Since this Javascript is executing in the client, you can just do the following:
document.location.hostname contains the hostname, and document.location.port the port. It's as easy as that.

Getting Client Ip on NODE.JS Through Cloudflare

I am currently using
data["ip"] = socket.client.conn.remoteAddress;;
But this will only show me the cloudflare IPs and I am not a fan of leaking my server's ip so how can I get my client's ip through cloudflare?
After me having to research for a couple of good hours I found out.
socket.client.request.headers['cf-connecting-ip']
This thread says that in socket.io 1+, you should be using:
socket.request.connection.remoteAddress
or:
socket.handshake.address
But, if there are cloudfare proxy servers in the path (which there presumably are), then this will only report the true client IP address if the cloudfare proxy servers set the appropriate header to the actual client IP address when they proxy the initial HTTP connection that initiates the socket.io connection.

how to use host name in the place of ip address in the socket programming in java?

I am using socket programming to connect two PCs in java through wi-fi. I used the ip address of the server at the client side. but the problem is that when the ip address of the server got changed then i have to change the ip address of server at client side. and when i use host name for connection nothing happens. is there any way to use static ip or any other solutions that can work to connect both of them which can work on any network. independent of ip address of the server.
please suggest me the solution.
i think there is a simple solution to your problem ...
you should get the ip address of your device by using Inetaddress.getbyName("user-pc").getHostAddress()
hope it will work for u...
1. First of all If you are on LAN, then Any IP from Class A, B, C will suffice, But if you want it over the Internet, then you will have to be careful about the Private and Public IPs.
2. For static IP over internet you need to contact you Internet Server Provider, or you can try out some sites over the net that provides static ip based on your dynamic ips.
3. But if you want that due to the change in your server ip the client code need NOT be changed then you can do the following...
- Use the Domain Name of the Server instead of IP, by using Domain Name Server.
- Instead of storing the raw IP of the Server in the Client code, use Some variable which gets the IP of the server from some file like the Property file, Database etc...
