title: Getting error while adding host=-only server in virtual box. [ E_INVALIDARG (0x80070057) ]
body: <p>I need to create a new Host-only network, in VirtualBox, as a part of this <a href="https://youtu.be/51f5uEPoZns?t=479" rel="nofollow noreferrer">tutorial</a> to learn Puppet tool. I went to <code>File -&gt; Preferences -&gt; Network -&gt; Host-only network</code>, and clicked on "Add host-only network". On clicking ok, <strong>it generated default values of DHCP as 0, in the end (screesnshots below).</strong> Which gave the following <strong>error</strong>:</p>
  
  <pre><code>Failed to save the settings.
  
  Invalid server address.
