iproute2 is a collection of user-space utilities used to communicate with various Linux kernel components over the netlink protocol. More specifically, the iproute2 utilities are used for controlling TCP and UDP IP networking and traffic control in the Linux kernel, in both IPv4 and IPv6 networks, as well as for configuring the device drivers for network interface controllers (NICs) and wireless network interface controllers (WNICs).

As of December 2013, iproute2 is maintained by Stephen Hemminger. The original author, Alexey Kuznetsov, was responsible for the Quality of Service (QoS) implementation in the Linux kernel.[2]

iproute2 collection contains the following command-line utilities: ip, ss, bridge, rtacct, rtmon, tc, ctstat, lnstat, nstat, routef, routel, rtstat and arpd.[3] tc is used for traffic control. Utilities in iproute2 are developed in parallel to the Linux kernel.

iproute2 is intended to replace an entire suite of standard Unix networking tools (often called "net-tools") that were previously used for the tasks of configuring network interfaces, routing tables, and managing the ARP table.[4]

Tools replaced by iproute2
Purpose Legacy net-tools iproute2
Address and link configuration ifconfig ip addr, ip link
Routing tables route ip route
Neighbors arp ip neigh
VLAN vconfig ip link
Tunnels iptunnel ip tunnel
Multicast ipmaddr ip maddr
Statistics netstat ss

iproute2 unifies the syntax for these various commands, which evolved over many years of Unix development.
