iproute2 5.8.0 Utilities for controlling TCP/IP networking and traffic in Linux

Iproute2 is a collection of utilities for controlling TCP/IP networking and traffic with the Linux kernel. The most important of these are ip, which configures IPv4 and IPv6, and tc for traffic control.

Most network configuration manuals still refer to ifconfig and route as the primary network configuration tools, but ifconfig is known to behave inadequately in modern network environments, and both should be deprecated.
