> If you are trying to do that in a custom Authenticator you can use the AuthenticationFlowContext. Depending if you’re using a reverse proxy the IP can come from one of the following methods: // no reverse proxy authenticationFlowContext.getHttpRequest().getRemoteAddress(); // with reverse proxy authenticationFlowContext.getHttpRequest().getHttpHeaders().getHeaderString("X-Forwarded-For");

If you are behind a proxy, you could send the X-Forwarded-For header, I’m quite sure there is a topic about that in the documentation
