Which company owns MAC address prefix 0C:8D:98?

MAC address prefix 0C:8D:98 is registered to TOP EIGHT IND CORP in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 0C:8D:98 has a network interface built by TOP EIGHT IND CORP.

What is the OUI 0C:8D:98?

0C:8D:98 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to TOP EIGHT IND CORP. It covers every address from 0C:8D:98:00:00:00 to 0C:8D:98:FF:FF:FF, or 16,777,216 addresses in total. It is also written 0C-8D-98.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 0C:8D:98:00:00:00 that is 0C:8D: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 TOP EIGHT IND CORP located?

TOP EIGHT IND CORP is listed at 8F.,No79-1 Zhouzi St., Neihu District, Taipei City (Neihu Technology Park) Taipei TW 11493 in the IEEE OUI registry entry for 0C:8D:98. This is the address the organization registered with the IEEE, which may differ from its current operating address.
