title: Why cant I ping a virtual guest from host by default
body: <p>I ran into some trouble when I tried to ping my Ubuntu virtual guest from my Windows 10 host, but this <a href="https://2buntu.com/articles/1513/accessing-your-virtualbox-guest-from-your-host-os/" rel="nofollow noreferrer">solution </a> did the trick.</p>
  
  <p>I'm wondering what exactly is a "host-only-adapter" and why cant the I ping the virtual machine by default? How exactly does the virtual machine access the internet when I cant ping it?</p>
