What this means
The IEEE assigned the MA-L block A0E025 to Provision-ISR. Every network interface they manufacture under this block has a MAC address beginning with these digits, followed by a unique per-device identifier. If a device on your network shows a MAC starting A0:E0:25, it is Provision-ISR hardware.
