Which company owns MAC address prefix 88:40:67?

MAC address prefix 88:40:67 is registered to infomark in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:40:67 has a network interface built by infomark.

What is the OUI 88:40:67?

88:40:67 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to infomark. It covers every address from 88:40:67:00:00:00 to 88:40:67:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-40-67.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:40:67:00:00:00 that is 88:40:67 — 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 infomark located?

infomark is listed at 3F. Humaxvillage, 216 Hwangsaeul-ro Seongnam-si KR 13595 in the IEEE OUI registry entry for 88:40:67. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does infomark own?

infomark holds 3 OUI prefixes in the IEEE registry, of which 88:40:67 is one. A device made by infomark could carry a MAC address from any of them.
