Which company owns MAC address prefix 80:03:0D?

MAC address prefix 80:03:0D is registered to CANON INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 80:03:0D has a network interface built by CANON INC..

What is the OUI 80:03:0D?

80:03:0D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to CANON INC.. It covers every address from 80:03:0D:00:00:00 to 80:03:0D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 80-03-0D.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 80:03:0D:00:00:00 that is 80:03:0D — 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 CANON INC. located?

CANON INC. is listed at 30-2 Shimomaruko 3-chome, Ohta-ku Tokyo JP 146-8501 in the IEEE OUI registry entry for 80:03:0D. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does CANON INC. own?

CANON INC. holds 25 OUI prefixes in the IEEE registry, of which 80:03:0D is one. A device made by CANON INC. could carry a MAC address from any of them.
