I'm trying to convert InetAddress.getLocalHost() to String but it gets a different address. When I use InetAddress.getLocalHost(), I get my real IP address, but when I use InetAddress.getLocalHost().toString() it's some different address that I don't know.

This is my code:

  String ipAddr = StringUtils.substringAfter((String) InetAddress.getLocalHost(), "/");
  String host = InetAddress.getLocalHost().getHostAddress();

My real IP address is 172.xxx.xxx.xxx, but when I convert to string, I get 168.xxx.xxx.xxx. How can I get my real IP address, that is, my IP address from my local machine?

What is actual output you receive in both cases? – luk2302 Apr 04 '21 at 18:44
@luk2302 my real ip adress starts with 172 and thats i get when i dont use conversion, but with conversion to string its starts with 192... – None Apr 04 '21 at 18:46
@luk2302 probably not - as OP clearly wants their external IP. – rzwitserloot Apr 04 '21 at 18:48
Oh, nevermind, they do seem to want the 172 address. – rzwitserloot Apr 04 '21 at 18:49
