MAC Address Analyzer

Identify the Vendor of devices on your network and analyze the structural properties (OUI, U/L Bit, I/G Bit) of the MAC address with engineering precision.

What is MAC Address and OUI?

A MAC (Media Access Control) address is the ID card of network devices. This 48-bit (6-byte) address starts with a 24-bit (3-byte) **OUI (Organizationally Unique Identifier)** that identifies the manufacturer. For example, `00:1A:2B` usually belongs to Cisco.

What is a Private (Local) MAC?

Modern mobile devices (iOS & Android) generate randomized MAC addresses when connecting to Wi-Fi to protect privacy. Our tool uses "U/L Bit" analysis to detect if an address is real hardware or a randomized virtual one.

Unicast vs Multicast

The least significant bit of the first byte (I/G bit) determines if traffic is meant for a single device (Unicast) or a group (Multicast). This distinction is vital for network troubleshooting.

MAC Address FAQ

Can I find an IP from a MAC address?
No. MAC addresses operate at Layer 2 (Data Link), while IPs are at Layer 3 (Network). You cannot find an IP from a MAC over the internet, only within a local network using ARP tables.
Can a MAC address be changed?
The physical address on the hardware cannot be changed, but it can be temporarily spoofed at the operating system level.
