Which company owns MAC address prefix 30:EB:25?

MAC address prefix 30:EB:25 is registered to INTEK DIGITAL in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 30:EB:25 has a network interface built by INTEK DIGITAL.

What is the OUI 30:EB:25?

30:EB:25 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to INTEK DIGITAL. It covers every address from 30:EB:25:00:00:00 to 30:EB:25:FF:FF:FF, or 16,777,216 addresses in total. It is also written 30-EB-25.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 30:EB:25:00:00:00 that is 30:EB:25 — 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 INTEK DIGITAL located?

INTEK DIGITAL is listed at 801, 8th Fl., Anyang K-center building, 1591-9 Anyang KR 431-060 in the IEEE OUI registry entry for 30:EB:25. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does INTEK DIGITAL own?

INTEK DIGITAL holds 2 OUI prefixes in the IEEE registry, of which 30:EB:25 is one. A device made by INTEK DIGITAL could carry a MAC address from any of them.
