What is a virtual network adapter?
A virtual network arranger is software that operates like a physical net arranger within the host operational system ( OS ) or through an application installed on the end point or waiter. Applications and services on the device or server can entree the virtual network arranger when a second network interface is needed but no forcible adapter is available .
A virtual network arranger can be used with a virtual private net ( VPN ). A VPN is a service that creates a secure network that extends a individual network across a populace network, such as the internet. It provides outback offices or users with batten access to the company network. A virtual network arranger separates the data flows that should be sent across the VPN burrow from the datum flows that should be sent from the local, physical network adapter .
A virtual network adapter can be used with a VPN to extend a private network across the internet.
virtual network adapters are a foundational component within hypervisor environments, such as the following :

- VMware’s vSphere and ESXi
- Microsoft’s Hyper-V
- Citrix Xen or Xen Server
- Kernel-based Virtual Machine
Each virtual server or desktop is a software copy of a physical waiter or desktop. These virtual machines must contain one or more virtual network adapters to talk to early devices on either coherent or physical networks that occupy outside the VM .
How does a virtual network adapter work?
virtual net adapters are created in one of three ways. The first method uses tools within the device OS to create a virtual adapter. For exemplar, Windows 10 has built-in functionality to create VPN virtual network adapters. A virtual network arranger for VPN purposes requires entirely a few bits of information regarding the connection name, the VPN head-end name or IP cover, the VPN type the head-end VPN server uses to communicate, and a pre-shared samara or similar authentication mechanism depending on how the VPN tunnels are configured .
Windows Device Manager can besides be used to manually configure virtual network adapters for a diverseness of reasons, including the loopback adapter — now called Microsoft KM-TEST Loopback Adapter in Windows 10 — for testing purposes or to manually configure hypervisor-specific adapters.

Another direction to create virtual adapters is with a third-party application. This type of application automatically builds a virtual network adapter within the device OS on the drug user ‘s behalf. It is utilitarian when the arranger serves a one purpose and does not require any special net configuration settings .
finally, in a virtualized desktop or waiter environment, the administrator can configure virtual networks and virtual network adapters to enable the VMs to communicate outside their virtual example. The configuration of the adaptors is performed through the hypervisor management interface during the VM setup processes. additionally, additions, deletions or changes can be performed using hypervisor management tools as needed .
What are the benefits of a virtual network?
virtual network adapters provide an extra network interface on a device without the indigence for a physical network interface menu ( NIC ).
By enabling an OS system to create new virtual interfaces, complex net designs and routing can occur within the OS, which was previously impossible without physical NICs. Segmenting dealings for security and link share are the most coarse function cases for virtual network adapters in desktop or ad hoc scenarios. virtual network adapters are a requirement in virtualized architectures .
Installing a virtual network adapter in Windows 10
There are several ways to install virtual network adapters, depending on need and purpose. For exercise, loopback virtual network adapters are normally used for troubleshooting and testing. In Windows 10, a loopback arranger can be installed using the following steps :
- From the Windows 10 search interface, type in Device Manager, and click on the result. Network adapters appears on the list.
- Click on the Action drop-down menu, and select Add legacy hardware.
- Click on Next on the Add Hardware Wizard, choose the manual install process radio button and click on Next. Select Network adapters from the list, and click on Next.
- Select Microsoft on the Manufacturer list and then Microsoft KM-TEST Loopback Adapter.
- Click on Next to confirm the installation and then Finish.
once completed, a new arranger will be visible in the Windows 10 Network Connections part of the Control Panel, and the arranger can be modified as needed. For model, the loopback adapter is set to use Dynamic Host Configuration Protocol by default. This can be well modified to configure an IP address manually, the same direction a physical interface is modified .
