Which company owns MAC address prefix 00:01:ED?

MAC address prefix 00:01:ED is registered to SETA Corp. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:01:ED has a network interface built by SETA Corp..

What is the OUI 00:01:ED?

00:01:ED is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SETA Corp.. It covers every address from 00:01:ED:00:00:00 to 00:01:ED:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-01-ED.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:01:ED:00:00:00 that is 00:01:ED — 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 SETA Corp. located?

SETA Corp. is listed at Ariake Frontier Bldg. B JAPAN JP 135-0063 in the IEEE OUI registry entry for 00:01:ED. This is the address the organization registered with the IEEE, which may differ from its current operating address.
