What is the OUI 90:DB:46?

90:DB:46 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to E-LEAD ELECTRONIC CO., LTD. It covers every address from 90:DB:46:00:00:00 to 90:DB:46:FF:FF:FF, or 16,777,216 addresses in total. It is also written 90-DB-46.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 90:DB:46:00:00:00 that is 90:DB:46 — 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 E-LEAD ELECTRONIC CO., LTD located?

E-LEAD ELECTRONIC CO., LTD is listed at NO.37, GUNGDUNG 1ST RD. SHENGANG SHIANG CHANGHUA TW 50971 in the IEEE OUI registry entry for 90:DB:46. This is the address the organization registered with the IEEE, which may differ from its current operating address.
