Which company owns MAC address prefix 58:F4:96?

MAC address prefix 58:F4:96 is registered to Source Chain in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 58:F4:96 has a network interface built by Source Chain.

What is the OUI 58:F4:96?

58:F4:96 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Source Chain. It covers every address from 58:F4:96:00:00:00 to 58:F4:96:FF:FF:FF, or 16,777,216 addresses in total. It is also written 58-F4-96.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 58:F4:96:00:00:00 that is 58:F4:96 — 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 Source Chain located?

Source Chain is listed at #407-4 eBIZ.Center Seoul seoul KR ASI|KR|KS013|SEOUL in the IEEE OUI registry entry for 58:F4:96. This is the address the organization registered with the IEEE, which may differ from its current operating address.
