Which company owns MAC address prefix 78:36:07?

MAC address prefix 78:36:07 is registered to Cermate Technologies Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 78:36:07 has a network interface built by Cermate Technologies Inc..

What is the OUI 78:36:07?

78:36:07 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Cermate Technologies Inc.. It covers every address from 78:36:07:00:00:00 to 78:36:07:FF:FF:FF, or 16,777,216 addresses in total. It is also written 78-36-07.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 78:36:07:00:00:00 that is 78:36:07 — 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 Cermate Technologies Inc. located?

Cermate Technologies Inc. is listed at 7F-1, No 168 Lien-Chen Rd. Chung-Ho Dist New Taipei City TW in the IEEE OUI registry entry for 78:36:07. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Cermate Technologies Inc. own?

Cermate Technologies Inc. holds 2 OUI prefixes in the IEEE registry, of which 78:36:07 is one. A device made by Cermate Technologies Inc. could carry a MAC address from any of them.
