Using The New iproute2 Suite

For years, even in 2015, web tutorials, college textbooks and lab simulators have all been teaching the traditional networking utilities, such as arp, ifconfig, netstat and route. Whether you know it or not, most of these commands were deprecated years ago. They were replaced with commands from the iproute2 suite of utilities. Most Linux distros have continued to install the traditional tools, but CentOS, Arch and now openSUSE (among others), are moving to put them into deprecated status. That means we’ll need to start getting used to the new tools.
