What this means
The IEEE assigned the MA-L block 001CD3 to ZP Engineering SEL. 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 00:1C:D3, it is ZP Engineering SEL hardware.
Frequently Asked Questions
Who owns MAC prefix 001CD3?
001CD3 is registered to ZP Engineering SEL in the IEEE MA-L registry.
What does the MA-L registry type mean?
An MA-L assignment, the IEEE's original OUI format, gives the vendor the first three octets and 16,777,216 device addresses under them. ZP Engineering SEL's block covers 16,777,216 addresses.
What devices use 001CD3?
