How to disable IPv6 on Cloudflare?

Cloudflare has IPv6 enabled by default on all sites. This is a good option as IPv6 provides a solution to resource depletion. However, it can occasionally cause problems with legacy systems. This article explains two methods to disable IPv6 on the site.

Method 1

We can disable IPv6 using Cloudflare API. The method consists of two steps:

1. API creation
2. API command Exceution

API creation

• We must first obtain an API Key before we can use the API. This can be done on the API Tokens User Profile page.
• We can select ‘Create Custom Token’ after pressing the ‘Create Token’ button.
• Then we must make a new token with ‘Edit’ permissions to ‘Zone Settings.’ This key can also be limited to a certain zone.
• We will now have access to an alphanumeric API Token after saving these changes. Save this unique code for the next step.

API command Exceution

We want CURL installed and a terminal/command line prompt open. Replace with the Zone ID from the Dashboard. Replace with the API Key from the previous step. Finally, execute the below command.

curl -X PATCH "https://api.cloudflare.com/client/v4/zones/<zone_id>/settings/ipv6" \
-H "Authorization: Bearer <token>" \
-H "Content-Type: application/json" \
--data '{"value":"off"}'

Thus IPv6 on the WordPress site is disabled successfully.

Method 2

In this method, we’re using cPanel to disable IPv6.

1. Firstly, we must log into the cPanel account.
2. Next, in the Software section, select Cloudflare.
3. Then, to access the account, click Sign in Here.
4. Next, select the Home menu.
5. Finally, the On/Off button is visible in front of IPv6 Compatibility. We should click it to enable or disable IPv6 compatibility support.
