What this means
The IEEE assigned the MA-L block 44666E to IP-LINE. 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 44:66:6E, it is IP-LINE hardware.
