Which company owns MAC address prefix E0:7F:88?

MAC address prefix E0:7F:88 is registered to EVIDENCE Network SIA in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E0:7F:88 has a network interface built by EVIDENCE Network SIA.

What is the OUI E0:7F:88?

E0:7F:88 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to EVIDENCE Network SIA. It covers every address from E0:7F:88:00:00:00 to E0:7F:88:FF:FF:FF, or 16,777,216 addresses in total. It is also written E0-7F-88.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E0:7F:88:00:00:00 that is E0:7F:88 — 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 EVIDENCE Network SIA located?

EVIDENCE Network SIA is listed at Zilupes 4A Rīga LV LV-1019 in the IEEE OUI registry entry for E0:7F:88. This is the address the organization registered with the IEEE, which may differ from its current operating address.
