What is the OUI 84:4F:03?

84:4F:03 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Ablelink Electronics Ltd. It covers every address from 84:4F:03:00:00:00 to 84:4F:03:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-4F-03.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:4F:03:00:00:00 that is 84:4F:03 — 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 Ablelink Electronics Ltd located?

Ablelink Electronics Ltd is listed at Flat 1602,16/F Kodak House 2 39 Healthy Street East, CN in the IEEE OUI registry entry for 84:4F:03. This is the address the organization registered with the IEEE, which may differ from its current operating address.
