Which company owns MAC address prefix 00:1E:58?

MAC address prefix 00:1E:58 is registered to D-Link Corporation in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:1E:58 has a network interface built by D-Link Corporation.

What is the OUI 00:1E:58?

00:1E:58 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to D-Link Corporation. It covers every address from 00:1E:58:00:00:00 to 00:1E:58:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-1E-58.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 00:1E:58:00:00:00 that is 00:1E:58 — 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 D-Link Corporation located?

D-Link Corporation is listed at NO.289, Sinhu 3rd Rd., Neihu District, Taipei City TW 114 in the IEEE OUI registry entry for 00:1E:58. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does D-Link Corporation own?

D-Link Corporation holds 27 OUI prefixes in the IEEE registry, of which 00:1E:58 is one. A device made by D-Link Corporation could carry a MAC address from any of them.
