Which company owns MAC address prefix 00:0E:68?

MAC address prefix 00:0E:68 is registered to E-TOP Network Technology Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:0E:68 has a network interface built by E-TOP Network Technology Inc..

What is the OUI 00:0E:68?

00:0E:68 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to E-TOP Network Technology Inc.. It covers every address from 00:0E:68:00:00:00 to 00:0E:68:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-0E-68.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:0E:68:00:00:00 that is 00:0E:68 — 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 E-TOP Network Technology Inc. located?

E-TOP Network Technology Inc. is listed at No. 7, Shin Shin Rd., Tainan TW 702 in the IEEE OUI registry entry for 00:0E:68. This is the address the organization registered with the IEEE, which may differ from its current operating address.
