Some Linux distributions have deprecated the use of ifconfig and route in favor of the software suite iproute2,[3] which has been available since 1999 for Linux 2.2.[4] iproute2 includes support for all common functions of ifconfig(8), route(8), arp(8) and netstat(1). It also includes multicast configuration support, tunnel and virtual link management, traffic control, and low-level IPsec configuration, among other features.
