Tip: To change interface names, see #Change interface name and #Revert to traditional interface names. Also note that ip commands can generally be abbreviated, for clarity they are however spelled out in this article.īy default udev assigns names to your network interfaces using Predictable Network Interface Names, which prefixes interfaces names with en (wired/ Ethernet), wl (wireless/WLAN), or ww ( WWAN). For persistent configuration, you can use a network manager or automate ip commands using scripts and systemd units. Be aware that configuration made using ip will be lost after a reboot. Iproute2 is a dependency of the base meta package and provides the ip(8) command-line interface, used to manage network interfaces, IP addresses and the routing table.
