Random MAC Generator
Generate a random and valid MAC address in the format XX:XX:XX:XX:XX:XX with manufacturer indication
What is a MAC address?
A MAC address (Media Access Control address) is a unique identifier assigned to a network interface for communication in the physical network segment. MAC addresses are used as the network address for most networking technologies including Ethernet, Wi-Fi and Bluetooth.
A MAC address is typically written as six pairs of hexadecimal digits separated by colons (e.g. 01:23:45:67:89:AB).
How is the manufacturer determined?
The first three bytes of a MAC address are called OUI (Organizationally Unique Identifier) and identify the equipment manufacturer:
| Prefix (OUI) | Manufacturer |
|---|---|
| 00:26:5E | Asustek Computer |
| 00:1B:FC | Nintendo |
| 00:1A:11 | Samsung Electronics |
| 00:0C:29 | VMware |
| 00:1C:B3 | Dell |
| 00:24:8C | Dell |
| 00:25:B3 | Apple |
| 00:22:5F | Cisco |
| 00:19:B9 | TP-LINK |
| 00:1D:7D | Sony |
| 00:13:10 | Linksys |
| 00:15:F2 | Microsoft |
| 00:1E:65 | HTC |
| 00:23:12 | Intel |
| 00:12:F0 | HP |
| A0:36:9F | Huawei |
| AC:87:A3 | Apple |
| BC:30:7E | Samsung |
| C8:3A:6B | Intel |
| D0:57:4C | Cisco |
| E4:42:A6 | TP-LINK |
| F0:79:59 | Apple |
| FC:15:B4 | Huawei |
Why generate a random MAC address?
Random MAC addresses can be useful for:
- Testing network applications and systems
- Ensuring privacy on public Wi-Fi networks (MAC randomization)
- Replacing the MAC address on a router or computer
- Network device simulation
- Device anonymization on the network
The generated MAC address is valid (unicast) and contains a real OUI (Organizationally Unique Identifier) from the database of known manufacturers. Each new request creates a unique address.
