'''iproute2''' is a collection of userspace utilities for controlling and monitoring various aspects of networking in the Linux kernel, including routing, network interfaces, tunnels, traffic control, and network-related device drivers.

==Project== iproute2 is an open-source project released under the terms of version 2 of the GNU General Public License. Its development is closely tied to the development of networking components of the Linux kernel. {{As of|2013|12}}, iproute2 is maintained by Stephen Hemminger and David Ahern. The original author, Alexey Kuznetsov, was responsible for the quality of service (QoS) implementation in the Linux kernel.<ref>{{cite web |url = https://wiki.linuxfoundation.org/networking/iproute2 |title = Introduction to iproute2 |date = November 19, 2009 |accessdate = July 15, 2019 |publisher = The Linux Foundation |df = mdy-all }}</ref>

iproute2 collection contains the following command-line utilities: ''arpd'', ''bridge'', ''ctstat'', ''dcb'', ''devlink'', ''ip'', ''lnstat'', ''nstat'', ''rdma'', ''routef'', ''routel'', ''rtacct'', ''rtmon'', ''rtstat'', ''ss'', ''tc'', ''tipc'' and ''vdpa''. <ref>{{cite web | url=https://packages.debian.org/sid/amd64/iproute2/filelist | title=list of the Debian package iproute2 | work=Debian}}</ref> ''tc'' is used for traffic control. iproute2 utilities communicate with the Linux kernel using the netlink protocol. Some of the iproute2 utilities are often recommended over now-obsolete ''net-tools'' utilities that provide the same functionality.<ref>{{cite web | url = https://lists.debian.org/debian-devel/2009/03/msg00780.html | title = net-tools future | date = March 15, 2009 | accessdate = March 21, 2019 | author = Martín Ferrari | website = debian.org }}</ref><ref>{{cite web | url=https://wiki.linuxfoundation.org/networking/net-tools | title=net-tools | publisher=The Linux Foundation}}</ref> Below is a table of obsolete utilities and their iproute2 replacements.
