Here is a quick guide for how we can find the IP address in different operating systems.
Windows
In pretty much every version of windows we can find the IP address easily using the command tool. Start buy pressing the windows key and R at the same time, then write 'cmd' and press enter.
You should now see a black box, here write 'ipconfig' and press enter.
A chunk of text will appear. Scroll upwards until you see the line:
IPv4-adress . . . . . . . . . . . :
The number followed that line is your computers IP address.
Mac / OSX
On the Mac you find the IP address by starting up the program called Terminal and in the black box you write 'ifconfig' and press enter.
Now look for the line saying 'inet'
The number followed that line is your computers IP address.
Linux
Finding the ip address in linux is as easy as on the Mac, in the terminal you only need to write 'ifconfig' or on some distros you might need to write '/sbin/ifconfig' and press enter.
Look for the line 'inet addr:'
The number on that line will be the ip address of your linux-machine.
