About MAC Addresses:
? MAC (Media Access Control) addresses are unique identifiers for network interfaces
? Format: 6 pairs of hexadecimal digits (48 bits)
? First 3 pairs identify the manufacturer (OUI - Organizationally Unique Identifier)
? Last 3 pairs are device-specific
? Used for testing, virtualization, and network configuration

Frequently Asked Questions

What is a MAC address?

A MAC (Media Access Control) address is a unique 48-bit hardware identifier assigned to network interfaces (WiFi, Ethernet). It's formatted as six pairs of hexadecimal digits (e.g., 00:1A:2B:3C:4D:5E).

Are generated MAC addresses unique?

While randomly generated MAC addresses have an extremely low probability of collision, they are not guaranteed to be globally unique like manufacturer-assigned addresses. They are suitable for testing and virtual machines.

What is the OUI in a MAC address?

The OUI (Organizationally Unique Identifier) is the first 3 bytes (24 bits) of a MAC address, assigned by IEEE to manufacturers. For example, 00:1A:2B is assigned to a specific company.
