<p>
The <b outputclass="bold">Network</b> section in a virtual
machine's <b outputclass="bold">Settings</b> window enables
you to configure how Oracle VM VirtualBox presents virtual network cards
to your VM, and how they operate.
</p>
<p>
When you first create a virtual machine, Oracle VM VirtualBox by default
enables one virtual network card and selects the Network Address
Translation (NAT) mode for it. This way the guest can connect to
the outside world using the host's networking and the outside
world can connect to services on the guest which you choose to
make visible outside of the virtual machine.
</p>
<p>
This default setup is good for the majority of Oracle VM VirtualBox
users. However, Oracle VM VirtualBox is extremely flexible in how it can
virtualize networking. It supports many virtual network cards per
virtual machine. The first four virtual network cards can be
configured in detail in VirtualBox Manager. Additional network cards can
be configured using the <userinput>VBoxManage</userinput> command.
</p>
<p>
Many networking options are available. See
<xref href="networkingdetails.dita#networkingdetails"/> for more information.
