What is the OUI 88:41:C1?

88:41:C1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to ORBISAT DA AMAZONIA IND E AEROL SA. It covers every address from 88:41:C1:00:00:00 to 88:41:C1:FF:FF:FF, or 16,777,216 addresses in total. It is also written 88-41-C1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 88:41:C1:00:00:00 that is 88:41:C1 — 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 ORBISAT DA AMAZONIA IND E AEROL SA located?

ORBISAT DA AMAZONIA IND E AEROL SA is listed at AV SHISHIMA HIFUMI, 2911 SAO JOSE DOS CAMPOS São Paulo BR 12244-000 in the IEEE OUI registry entry for 88:41:C1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
