macchanger
Changes interface MAC addresses for lab privacy and filter testing.
Authorized testing only. Practice on systems you own, isolated labs, or targets with written permission. Unauthorized access is illegal.
When
Testing MAC filters on your own Wi-Fi AP or lab isolation demos.
How
Bring interface down; set random/vendor MAC; bring up; reconnect.
Why
MAC filters are weak controls — prove it safely on your gear.
Commands & usage
sudo ip link set wlan0 down
sudo macchanger -r wlan0
sudo ip link set wlan0 up
macchanger -s wlan0
Commands are educational examples. Adapt hosts, paths, and rates to your authorized scope.
