Fix – WordPress Showing Localhost IP( for Comment Author Instead of Real

This tutorial will address a problem where WordPress is displaying the local host IP address ( for the author of a comment instead of its actual IP address.

We will first diagnose the cause of the problem and then provide a step-by-step solution to fix it. We will also discuss the importance of accurate IP address tracking for security and moderation purposes.

By the end of this tutorial, you will have solved the problem and be able to accurately track the IP addresses of commenters on your WordPress website. This is a must-read for anyone experiencing this problem and looking for a solution.

So, you are using Varnish? Cool! That’s why you are unable to see real IP of your visitors. No worries, here’s the complete solution.

comment author ip

To fix this problem,

  1. Login to FTP/SFTP
  2. Go to public_html folder
  3. Edit wp-config.php
  4. Add below code just before /* That’s all, stop editing! Happy blogging. */
  5. Save Changes.
/** Required Code for showing correct IP address */
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])) { 
$xffaddrs = explode(',',$_SERVER['HTTP_X_FORWARDED_FOR']); 
$_SERVER['REMOTE_ADDR'] = $xffaddrs[0]; 

Mark: This little problem I had faced on Cloudways web hosting.

Alternative case

Similarly, if your IP is showing incorrect after using Cloudflare, here’s the fix –

/** Correct IP in case of Cloudflare **/
if(array_key_exists('HTTP_CF_CONNECTING_IP', $_SERVER)){ 

Alternatively, if you have LEMP stack with root access, then add below rule under Server Block. You can find your configuration file at /etc/nginx/sites-available/ directory.

server {
root /var/www/html;
index index.php index.html index.htm;
# Get real IP
set_real_ip_from ::/0;
real_ip_header X-Forwarded-For;

In case, if you don’t feel comfort in editing wp-config.php file, add above snippet using Code Snippets plugin. It will work fine. I hope this guide helps in the right direction. Thanks

  1. That’s the exact problem I was facing. The Cloudways support did rectify it twice but they never shared the solution. It was Mustasaam who referred me to this page.

    The solution works perfectly for me. Thank you for sharing.

    Just one more query, how did you hide the Website option from the comments box? Most of my readers are internet noobs who feel filling out the Website section is mandatory. I too want to get the same removed. Mind sharing an article on my email ID?

    • Thanks for visiting.

      To hide website field, you can use below snippet.

      // Remove URL Field
      function remove_url_comments($fields) {
      return $fields;

      Thanks for coming back.

      You need to put code just before this line
