Hi there,
Does anyone know how to get the Local Net Ip Address from a Remote Client in java?
thx

A:
Is this what you are looking for?
InetAddress addr = InetAddress.getLocalHost();
byte[] ipAddr = addr.getAddress(); // Get IP Address
String hostname = addr.getHostName(); // Get hostname
That gets the IP of the machine the code is running on.

A:
Assuming you mean getting the local IP address of a client running behind NAT, you can only do that with the client's cooperation, meaning you have to send it yourself.
What do you need it for anyway?

@Bart: Don't ask why he needs it. People makes a lot of projects. And you know it is very irritating (can't find a better word in English) when they ask you for what you need what you are asking for.

I don't ask it without a reason. The local IP seems an odd thing to need to know. If we know why he thinks he needs it, we may have better answers.

Jeje... well..the idea is that I have a server with a web app in a net and the client in another, so.. for example, if the client is in a building A and server in building B, thus the public ip of the building A, I need to know the subnet where the user connect to the app.Any sugestion?

But I wonder, why would you need the subnet of the client? I hope it's not for something related to security, because it's not safe.
