What is the OUI 48:B8:DE?

48:B8:DE is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to HOMEWINS TECHNOLOGY CO.,LTD.. It covers every address from 48:B8:DE:00:00:00 to 48:B8:DE:FF:FF:FF, or 16,777,216 addresses in total. It is also written 48-B8-DE.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 48:B8:DE:00:00:00 that is 48:B8:DE — 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 HOMEWINS TECHNOLOGY CO.,LTD. located?

HOMEWINS TECHNOLOGY CO.,LTD. is listed at 10F-1, NO. 122, QIAOHE RD., NEW TAIPEI CITY, TW 235 in the IEEE OUI registry entry for 48:B8:DE. This is the address the organization registered with the IEEE, which may differ from its current operating address.
