Which company owns MAC address prefix 88:73:98?

MAC address prefix 88:73:98 is registered to K2E Tekpoint in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:73:98 has a network interface built by K2E Tekpoint.

What is the OUI 88:73:98?

88:73:98 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to K2E Tekpoint. It covers every address from 88:73:98:00:00:00 to 88:73:98:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-73-98.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:73:98:00:00:00 that is 88:73:98 — 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 K2E Tekpoint located?

K2E Tekpoint is listed at 201,Winstower,278-51,Sungsoo2ga 3dong,Sungdong-gu,Seoul,S.Korea,133-123 Seoul Sungdong-gu KR 133-123 in the IEEE OUI registry entry for 88:73:98. This is the address the organization registered with the IEEE, which may differ from its current operating address.
