Get User IP Address in Twig Template

Question

Is there a way to get the user's IP address in a twig template? All the twig examples I find say to do it like this:

{% set ipAddr = app.request.server.get("REMOTE_ADDR") %}

But this variable always returns NULL. These examples aren't specific to Drupal so I'm guessing part of the Drupal implementation blocks/omits this.

Suppose you want to get the ip in the page.html.twig file.

in your

YOURTHEME.theme

you can try

use Symfony\Component\HttpFoundation;

function YOURTHEME_preprocess_page(&$variables) {
  $variables['page']['ip'] = \Drupal::request()->getClientIp();

}

in your template

page.html.twig

you can try:

{{ page.ip }}
