What is the difference between IPv4 and IPv6?

IPv4 and IPv6 are the two versions of the Internet Protocol, which acts as the "postal system" for the internet by assigning a unique address to every connected device.

The main difference between them is age, size, and the enormous number of addresses they can provide. Think of it like the difference between a 7-digit phone number and a 30-digit one.

Why This Matters for Click Fraud Protection

The internet is in a long-term transition from IPv4 to IPv6.

oday, your website receives traffic from both systems simultaneously.

Fraudsters and botnets don't limit themselves to one protocol; they will exploit any available network to launch attacks. Therefore, any effective fraud detection system must be able to handle both.

ClickSambo is built to track and analyze both IPv4 and IPv6 addresses seamlessly. By monitoring traffic from both protocols, we ensure there are no blind spots in your defense, providing complete protection regardless of how a fraudulent user connects to the internet.
