CommandLinux

ip

ip [object] [command] (objects: addr, link, route, etc.)

The modern Linux tool for viewing and configuring network interfaces, addresses, and routing — the intended replacement for ifconfig.

// FLAGS

addr showlist interfaces and IPs

link set eth0 upbring an interface up

route showshow the routing table

// EXAMPLE

ip addr show — lists every network interface with its assigned IP addresses.

// GOTCHA

The unified ip command replaces several older single-purpose tools (ifconfig, route, arp) at once — muscle memory from ifconfig-based tutorials doesn't map 1:1, since the verb/object order is reversed (ip addr show eth0 vs. ifconfig eth0).
