What is a MAC Address?

If an IP address is like a device's temporary mailing address, a MAC (Media Access Control) address is like its unique, unchangeable serial number

It’s a permanent hardware identifier burned into a device's network card (e.g., its Wi-Fi or Ethernet adapter) by the manufacturer. While an IP address can change each time a device connects to a new network, the MAC address remains fixed to that specific piece of hardware.

How ClickSambo Uses It for Advanced Protection

This permanence makes the MAC address an incredibly powerful tool for fraud protection.

A savvy fraudster can easily change their IP address to circumvent a standard block. However, ClickSambo's advanced systems can recognize the device's underlying MAC address. By blocking it, we can stop a specific fraudulent device from harming your campaigns, no matter how many times it changes its IP address or network.

This device-level blocking provides a more robust and persistent layer of security, stopping bad actors at the source.
