The lower layers of the OSI model consist of the physical layer, the data link layer, and
the network layer. They are commonly referred to as the heartbeat of a network and utilize
routing and switching protocols to move data across the network. Whether that network be IPv4
or IPv6 these layers functions do not change. Every network interface needs a way to identify
itself and MAC or Media Access Control addresses are the answer to that. These addresses are
unique to the network interface card they operate on and are burned in at the time the hardware is
manufactured. Beyond the hardware, protocols are utilized to keep the way data is translated and
transferred uniform across every capable network. These protocols each have their own specific
set of tasks and some like ICMP can even troubleshoot IP issues that may arise.
MAC addresses are unique to the organization that produces the specific piece of
hardware that is attempting to connect and communicate with a network. There are a total of
48its in each address and each address can be split into two identifying parts. The first three
octets label the manufacturer information while the last three octets denote the network interface
controller. Each NIC has its own specific MAC address allowing multiple NICs of the same
manufacturer to operate on the same network. The most commonly used local area technologies
like Ethernet use MAC addresses as a primary form of physical addressing which allows network
interface controllers to not only find each other on a network but transfer data directly to and
from the destination of choice.
IPv4 and IPv6 are the backbone of the internet and act as street addresses of the cyber
world. IPv4 is the most commonly used internet protocol and runs on a 32 bit architecture with a
