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].
Configuring an alias IP[edit]
Activities[edit]
- Show interface configuration in Linux including ip addresses:
ifconfig -aorip a - Show interface Ethernet network capabilities of your interface, such as speed, with:
mii-tool -v YOUR_INTERFACE_NAME,mii-tool -v eth0 - Show all network interfaces in Linux:[3]
- Learn about Linux Naming Schemes Hierarchy.
- Change your MAC address:
ifconfig {eth0|wlan0} hw ether CA:CA:CA:CA:CA:CA - macOS:
ipconfig getifaddr en0
