Which company owns MAC address prefix E8:C1:D7?

MAC address prefix E8:C1:D7 is registered to Philips in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with E8:C1:D7 has a network interface built by Philips.

What is the OUI E8:C1:D7?

E8:C1:D7 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Philips. It covers every address from E8:C1:D7:00:00:00 to E8:C1:D7:FF:FF:FF, or 16,777,216 addresses in total. It is also written E8-C1-D7.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in E8:C1:D7:00:00:00 that is E8:C1:D7 — 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 Philips located?

Philips is listed at TussenDiepen 4 Drachten Friesland NL 9206 AD in the IEEE OUI registry entry for E8:C1:D7. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Philips own?

Philips holds 2 OUI prefixes in the IEEE registry, of which E8:C1:D7 is one. A device made by Philips could carry a MAC address from any of them.
