MAC Address Generator

This lesson is part of Web Developer Tools · All levels

Summary

MAC Address Generator creates a random 48-bit MAC address in the form of a colon, hyphen, or point notation. This address is useful for network testing, documentation, device simulation, and virtual machine configuration. It's best to use locally administered bits to avoid colliding with real physical device addresses.

Key points

MAC address is 48 bits or 12 hexadecimal digits long
The I/G bit in the first octet distinguishes between unicast and multicast
The U/L bit marks the local address, usually 0x02 on the first octet
Common format among others 02:1A:2B:3C:4D:5E
Don't use real MAC belonging to someone else for networking activities.
