ip addr

IP Address Management - Modern Linux Network Tool

What Does It Do?

The ip addr command is part of the iproute2 suite and is the modern replacement for the older ifconfig command. It displays and manages IP addresses, network interfaces, and routing information on Linux systems.

The ip command provides more detailed information and additional features compared to ifconfig, supporting both IPv4 and IPv6 configurations.
