This post is a collection of my notes on installing and configuring Kernel-based Virtual Machine virtualization on a Debian 8 host. I control the VMs from my Ubuntu 16.10 desktop.
What is a MAC address?
A MAC (Media Access Control) address is a unique identifier for network interfaces. It is a 48-bit number (12 hexadecimal characters). The network card on your system has a built-in, unique address called the MAC address. The Address Resolution Protocol (ARP) maps an IP address (Network Layer – Layer 3) to a MAC Address (Data Link Layer – Layer 2).
An organizationally unique identifier (OUI) is a 24-bit number that uniquely identifies the manufacturer of the network card.
