What is Ifconfig? Ifconfig is a system administration utility in Unix-like operating systems for network interface configuration. The utility is a command line interface tool and is also used in the system startup scripts of many operating systems. When Terminal has launched, type the following command: ipconfig getifaddr en0 (to find your IP address if you are connected to a wireless network) or ipconfig getifaddr en1 (if you are connected to an Ethernet). If you are using Mac OS X, the command ipconfig grep inet displays detailed information about your computer signification in the.

The ipconfig command first appeared in Mac OS X Version 10.0 Public Beta. Mac OS X July 14, 2004 Mac OS X cheers, -84.77.134.92 20:52, 26 October 2006 (UTC) Note that Mac OSX, as recently as 10.3, also has an ifconfig command. I don't have an OSX box handy at the moment, but I bet ipconfig is a symlink to or a wrapper for ifconfig. The ipconfig (short for IP Configuration) is a basic, yet popular, Windows network command-line utility used to display the TCP/IP network configuration of a computer.If you are familiar with Linux, this tool is similiar to ifconfig.This tool is often used for troubleshooting network connectivity issues.

Ipconfig All On Mac

How to flush DNS cache in Internet Explorer: actually, you don't have to do anything on IE's side.

Simply clear Windows DNS cache (previously explained in this same post), then close Internet Explorer (if it is already open), and simply open it again. Flushing Windows DNS cache and restarting the browser is all that you need to do in this case.

The ipconfig command is used on Windows, while the ifconfig command is used on Linux, Mac OS X, and other Unix-like operating systems. These commands allow you to configure your network interfaces and view information about them.

For example, you can use the ipconfig /all command on Windows to view all your configured network interfaces, their IP addresses, DNS servers, and other information.

Or, you can use the ipconfig /flushdns command to flush your DNS cache, forcing Windows to get new addresses from its DNS servers every time you contact a new hostname. Other commands can force your computer to release its IP address and get a new one from its DHCP server. This utility can quickly display your computer’s IP address or help you troubleshoot problems.
