Which company owns MAC address prefix 88:C3:B3?

MAC address prefix 88:C3:B3 is registered to SOVICO in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 88:C3:B3 has a network interface built by SOVICO.

What is the OUI 88:C3:B3?

88:C3:B3 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SOVICO. It covers every address from 88:C3:B3:00:00:00 to 88:C3:B3:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-C3-B3.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:C3:B3:00:00:00 that is 88:C3:B3 — 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 SOVICO located?

SOVICO is listed at 2271-5 Nambusunhwan-ro, Seocho-gu Seoul KR 06703 in the IEEE OUI registry entry for 88:C3:B3. This is the address the organization registered with the IEEE, which may differ from its current operating address.
