list all ip address of all devices connected java

Question

I write a client-socket program and make chat between different devices

but if i wanted to connect two device on network I Establised through CMD,

so if I Create Socket and bind to it such IP and Port

Socket clientSocket = new Socket("127.0.0.1", 6000);

i should replace the IP ( 127.0.0.1 ) to the IP of the anther machine in the network

Is there's a way to list all IPS in the network to select from it to put the IP automatically in the Sokect ?

Not as far as I know. It seems like listing all the websites you can visit from your browser. The list would be huge. — clinomaniac, Dec 02 '17 at 00:12
Your question is unclear - have you read any of the thousands of articles about basic socket programming available? — stdunbar, Dec 02 '17 at 00:28
I already study Socket Programming and make an application on it — Sameh Mohamed Omr, Dec 02 '17 at 00:30
the problem is how to get the IP of anther user connected in the same network with me .. to send Packet to him with such message — Sameh Mohamed Omr, Dec 02 '17 at 00:31
Take a look at the first result on Google for [java simple client server program](http://cs.lmu.edu/~ray/notes/javanetexamples/) - it should give you some directional help. The server is given the client address during the connection process. — stdunbar, Dec 02 '17 at 00:46

You can use the approach mentioned in this post:

You can call these methods from your program using

Runtime.getRuntime().exec(command);

Hope this helps.

I think this solution suitable for Linux , I am using windows 10 – Sameh Mohamed Omr Dec 02 '17 at 00:26
What if this is run in a class A network? In that case there are a bit over 16 million addresses. How long do you think this will take to run? – stdunbar Dec 02 '17 at 00:26
@stdunbar I have mentioned that in the first comment to the question. This was to be used with caution. – clinomaniac Dec 11 '17 at 23:05
