Which company owns MAC address prefix 70:E1:FD?

MAC address prefix 70:E1:FD is registered to FLEXTRONICS in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 70:E1:FD has a network interface built by FLEXTRONICS.

What is the OUI 70:E1:FD?

70:E1:FD is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to FLEXTRONICS. It covers every address from 70:E1:FD:00:00:00 to 70:E1:FD:FF:FF:FF, or 16,777,216 addresses in total. It is also written 70-E1-FD.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 70:E1:FD:00:00:00 that is 70:E1:FD — 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 FLEXTRONICS located?

FLEXTRONICS is listed at Carretera Base Aerea 5850 int 4 Zapopan Jalisco MX 45136 in the IEEE OUI registry entry for 70:E1:FD. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does FLEXTRONICS own?

FLEXTRONICS holds 3 OUI prefixes in the IEEE registry, of which 70:E1:FD is one. A device made by FLEXTRONICS could carry a MAC address from any of them.
