Which company owns MAC address prefix 00:26:87?

MAC address prefix 00:26:87 is registered to corega K.K in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:26:87 has a network interface built by corega K.K.

What is the OUI 00:26:87?

00:26:87 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to corega K.K. It covers every address from 00:26:87:00:00:00 to 00:26:87:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-26-87.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:26:87:00:00:00 that is 00:26:87 — 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 corega K.K located?

corega K.K is listed at 1-19-20, Shinyokohama Yokohama-city Kanagawa-ken JP 222-0033 in the IEEE OUI registry entry for 00:26:87. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does corega K.K own?

corega K.K holds 2 OUI prefixes in the IEEE registry, of which 00:26:87 is one. A device made by corega K.K could carry a MAC address from any of them.
