will see an IP address that starts with "inet addr" followed by an IP address of the type 192.168.2.2. This is a default IP address format that we often reference in this article.
Now you have an IP address that can connect Raspberry Pi to your computer. If you are using Mac, you already have built-in SSH, start your terminal application and enter:
Ssh pi@192.
