How can i find out the ip address of the machine in Java

[ying lam]

Hi,

How can I find out the real ip address of the machine running my java program:

I tried this:
http://www.exampledepot.com/egs/java.net/Local.html

But it gives me 127.0.0.1, I need to know the real ip address of the machine that my Java program is running on.

Thank you.

Perhaps you didn't know that your machine can have more than one IP address. For example if you have an Ethernet cable connection and a wireless network connection, they have different IP addresses.

Anyway, there's a getAllByName(host) method in the InetAddress class that might help you.

try this:

  
 InetAddress   in  = InetAddress.getLocalHost();
 InetAddress[] all = InetAddress.getAllByName(in.getHostName());
 for (int i=0; i<all.length; i++) {
     System.out.println("  address = " + all[i]);
 }
