While the control panel is open. its a good time to configure the new (virtual) network adapter. We can configure the new Network just like a physical network. Go to Network and Sharing Center on the control panel
On the Network and Sharing Center, click Manage network connections.
Find the Network connection with labels as Microsoft Loopback Adapter, right click, then choose properties.

On my virtual network, I will be using IPv4 only for now. Choose Internet Protocol Version 4 (TCP/IPv4), then click properties.
I’m using a static network, and I will use the 10.10.10.10/ 24 block. Using this series, I dont want to conflict the existing physical network. My subnet mask is 255.255.255.0 and the DNS server (127.0.0.1). Click Ok. Then close the wizard.
