Which company owns MAC address prefix 04:FF:51?

MAC address prefix 04:FF:51 is registered to NOVAMEDIA INNOVISION SP. Z O.O. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 04:FF:51 has a network interface built by NOVAMEDIA INNOVISION SP. Z O.O..

What is the OUI 04:FF:51?

04:FF:51 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to NOVAMEDIA INNOVISION SP. Z O.O.. It covers every address from 04:FF:51:00:00:00 to 04:FF:51:FF:FF:FF, or 16,777,216 addresses in total. It is also written 04-FF-51.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 04:FF:51:00:00:00 that is 04:FF:51 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is NOVAMEDIA INNOVISION SP. Z O.O. located?

NOVAMEDIA INNOVISION SP. Z O.O. is listed at WODNA 7 KALISZ WIELKOPOLSKA PL 62-800 in the IEEE OUI registry entry for 04:FF:51. This is the address the organization registered with the IEEE, which may differ from its current operating address.
