Which company owns MAC address prefix 8C:87:26?

MAC address prefix 8C:87:26 is registered to VAST Data Inc in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 8C:87:26 has a network interface built by VAST Data Inc.

What is the OUI 8C:87:26?

8C:87:26 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to VAST Data Inc. It covers every address from 8C:87:26:00:00:00 to 8C:87:26:FF:FF:FF, or 16,777,216 addresses in total. It is also written 8C-87-26.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 8C:87:26:00:00:00 that is 8C:87:26 — 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 VAST Data Inc located?

VAST Data Inc is listed at 240 W 37th St New York NY US 10018 in the IEEE OUI registry entry for 8C:87:26. This is the address the organization registered with the IEEE, which may differ from its current operating address.
