Getting ready
We only need the ip and arping command-line tools to perform this process. These utilities may not be present by default, so install them before you continue.
If you are on a Debian or Ubuntu system, issue this command:
sudo apt-get install iproute arping
Red Hat and CentOS users can use this:
sudo yum install iproute iputils
Previous versions of this recipe used the ifconfig tool instead. This has been deprecated in favor of ip based on recent Linux distribution trends.
