How to get the IP address of a machine in Java [duplicate]

Question

Is there a way that I can get the ip address of a machine in Java? To get the IP address from the machine where my jar file is running?

Answer 1

The best answer is:

InetAddress.getLocalHost().getHostAddress();

(The getLocalHost method is declared in InetAddress not Inet4Address.)

It is also worth nothing that getLocalHost() does some security checks, so this may not work if your JAR is run in a sandbox.
