Hi,
The link “What is my IP adress” detect an IPV6 adress, but the plugin detect an IPV4 adress. I don’t know what to do about my setting. When I go to diagnostic tab “Server Environment Variables” there is no line with my IP adress IPV6 and I don’t understand what to put in define(‘CERBER_IP_KEY’, ‘???’ );
First of all, there’s no issue here. You do not need to use CERBER_IP_KEY.
This situation can happen if your computer has two IP addresses: an IPv4 and an IPv6 because it’s connected to a network that supports both protocols (Dual Stack). When you visit your website, your computer asks the DNS server for the site’s IP address. If your web server or the DNS of your domain only supports an IPv4 address, your computer uses this IPv4 to connect to your website. That’s why WP Cerber detects your computer’s IP address as IPv4.
When you open the “What is my IP address?” page on wpcerber.com, our DNS server offers both IPv4 and IPv6 addresses (A and AAAA records) because our web server supports both protocols. Modern computers like yours use a system called “Happy Eyeballs,” which helps them quickly choose the best protocol based on what’s available and performs better. Since IPv6 is a newer and more advanced protocol, your computer typically prefers it whenever possible. That’s why you see two different IP addresses on your website and on the “What is my IP address?” page.
This behavior isn’t an error but a normal feature of networks that support both protocols. Your computer simply uses different protocols depending on the configuration and availability of the servers it interacts with.
We’ll enhance IP detection on the "What is my IP address? " page to detect and display both IPv4 and IPv6 addresses simultaneously.
Thanks for your quick response
