FAQ
- Which company owns MAC address prefix 00:04:7D?
- MAC address prefix 00:04:7D is registered to Motorola Solutions Inc. in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 00:04:7D has a network interface built by Motorola Solutions Inc..
- What is the OUI 00:04:7D?
- 00:04:7D is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Motorola Solutions Inc.. It covers every address from 00:04:7D:00:00:00 to 00:04:7D:FF:FF:FF, or 16,777,216 addresses in total. It is also written 00-04-7D.
- How do I find the manufacturer of a MAC address?
- Take the first three octets of the address — in 00:04:7D:00:00:00 that is 00:04:7D — 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 Motorola Solutions Inc. located?
- Motorola Solutions Inc. is listed at 500 W Monroe Street, Ste 4400 Chicago IL US 60661-3781 in the IEEE OUI registry entry for 00:04:7D. This is the address the organization registered with the IEEE, which may differ from its current operating address.
- How many MAC prefixes does Motorola Solutions Inc. own?
- Motorola Solutions Inc. holds 4 OUI prefixes in the IEEE registry, of which 00:04:7D is one. A device made by Motorola Solutions Inc. could carry a MAC address from any of them.
