Which company owns MAC address prefix E8:78:A1?

MAC address prefix E8:78:A1 is registered to BEOVIEW INTERCOM DOO in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E8:78:A1 has a network interface built by BEOVIEW INTERCOM DOO.

What is the OUI E8:78:A1?

E8:78:A1 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to BEOVIEW INTERCOM DOO. It covers every address from E8:78:A1:00:00:00 to E8:78:A1:FF:FF:FF, or 16,777,216 addresses in total. It is also written E8-78-A1.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E8:78:A1:00:00:00 that is E8:78:A1 — 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 BEOVIEW INTERCOM DOO located?

BEOVIEW INTERCOM DOO is listed at TRESNJINOG CVETA 5/17 BELGRADE RS 11070 in the IEEE OUI registry entry for E8:78:A1. This is the address the organization registered with the IEEE, which may differ from its current operating address.
