Questions tagged [ifconfig]

ifconfig (short for interface configuration) is a system administration utility in Unix-like operating systems to configure, control, and query TCP/IP network interface parameters from a command line interface (CLI) or in system configuration scripts. Ifconfig originally appeared in 4.2BSD as part of the BSD TCP/IP suite.

You can use the ifconfig command to assign an address to a network interface and to configure or display the current network interface configuration information.
