ifconfigis a command in Unix-like operating systems like Linux[1], FreeBSD, OpenBSD, macOS for Ethernet network interface configuration.


In macOS, the ifconfig command functions as a wrapper to the IPConfiguration agent, and can control the BootP and DHCP clients from the command-line. Use of ifconfig to modify network settings in Mac OS X is discouraged, because ifconfig operates below the level of the system frameworks which help manage network configuration. To change network settings in Mac OS X from the command line, use /usr/sbin/ipconfig or /usr/sbin/networksetup.

ifconfig command is included in the net-tools package but not installed by default in RHEL since version 7[2].
