Which company owns MAC address prefix 08:00:31?

MAC address prefix 08:00:31 is registered to LITTLE MACHINES INC. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 08:00:31 has a network interface built by LITTLE MACHINES INC..

What is the OUI 08:00:31?

08:00:31 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to LITTLE MACHINES INC.. It covers every address from 08:00:31:00:00:00 to 08:00:31:FF:FF:FF, or 16,777,216 addresses in total. It is also written 08-00-31.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 08:00:31:00:00:00 that is 08:00:31 — 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 LITTLE MACHINES INC. located?

LITTLE MACHINES INC. is listed at 4141 JUTLAND DRIVE SAN DIEGO CA US 92117 in the IEEE OUI registry entry for 08:00:31. This is the address the organization registered with the IEEE, which may differ from its current operating address.
