FAQ
- Which company owns MAC address prefix 68:47:24?
- MAC address prefix 68:47:24 is registered to EM Microelectronic in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 68:47:24 has a network interface built by EM Microelectronic.
- What is the OUI 68:47:24?
- 68:47:24 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to EM Microelectronic. It covers every address from 68:47:24:00:00:00 to 68:47:24:FF:FF:FF, or 16,777,216 addresses in total. It is also written 68-47-24.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 68:47:24:00:00:00 that is 68:47:24 — 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 EM Microelectronic located?
- EM Microelectronic is listed at Rue des Sors 3 Marin-Epagnier Neuchatel CH 2074 in the IEEE OUI registry entry for 68:47:24. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does EM Microelectronic own?
- EM Microelectronic holds 74 OUI prefixes in the IEEE registry, of which 68:47:24 is one. A device made by EM Microelectronic could carry a MAC address from any of them.
