Definition
Each Ethernet device has a unique Ethernet address (sometimes called a MAC address). The
address appears as twelve digits separated by colons (for example, xx:xx:xx:xx:xx:xx). It is
usually on a label on the device itself.
Each digit is a number in hexadecimal (0 to 9 or A through F). No other device in the world will
have the same address, and it can not be changed.
You use the Ethernet address to identify a device so you can assign it an IP address.
In addition to the Ethernet address, an IP address identifies a node on an Ethernet network.
The IP address can be manually set. or you can use special software to automatically assign it.
An IP Address consists of four decimal integers separated by periods (xxx.xxx.xxx.xxx). Each xxx
is a decimal value from 0...255. For example, an IP Address could be 192.168.1.092 The
selection of IP Addresses is beyond the scope of this quick start, so please contact your
network administrator or use the ones provided in the examples.
Once you set an IP address for a device, you generally reference the device by its IP address.
The examples in this quick start use IP Addresses to define communication paths to the
devices.
