What is the OUI 18:4E:94?

18:4E:94 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to MESSOA TECHNOLOGIES INC.. It covers every address from 18:4E:94:00:00:00 to 18:4E:94:FF:FF:FF, or 16,777,216 addresses in total. It is also written 18-4E-94.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 18:4E:94:00:00:00 that is 18:4E:94 — 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 MESSOA TECHNOLOGIES INC. located?

MESSOA TECHNOLOGIES INC. is listed at 13611 12th St., Unit B Chino CA US 91710 in the IEEE OUI registry entry for 18:4E:94. This is the address the organization registered with the IEEE, which may differ from its current operating address.
