Which company owns MAC address prefix 98:BC:99?

MAC address prefix 98:BC:99 is registered to Edeltech Co.,Ltd. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 98:BC:99 has a network interface built by Edeltech Co.,Ltd..

What is the OUI 98:BC:99?

98:BC:99 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Edeltech Co.,Ltd.. It covers every address from 98:BC:99:00:00:00 to 98:BC:99:FF:FF:FF, or 16,777,216 addresses in total. It is also written 98-BC-99.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 98:BC:99:00:00:00 that is 98:BC:99 — 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 Edeltech Co.,Ltd. located?

Edeltech Co.,Ltd. is listed at #302 Jamae Bldg, 1010-28, Sadang-dong, Dongjak=gu Seoul KR 156-824 in the IEEE OUI registry entry for 98:BC:99. This is the address the organization registered with the IEEE, which may differ from its current operating address.
