What this means
The IEEE assigned the MA-L block 38EADD to Juniper Networks. 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 38:EA:DD, it is Juniper Networks hardware.
