Virtual switches/ Hyper-V VLAN you can create 3 different types of virtual switches depending the needs of your virtual machines and one single machine can use multiple virtual NICs that is member of different Virtual Switches.
External This virtual switch binds to the physical network adapter and create a new adapter you can 1. see in Control Panel\Network and Internet\Network Connections so if a virtual machine needs contact outside the host machine this one is a must.
Internal This virtual switch can be used to connect all virtual machines and the host machine but can- 2. not go outside that.
Private This virtual switch can only be used by the virtual host 3. Further information:

Private will not allow communication with the host machine. External will allow communication with the host machine but also allow access to other machines on the host machine’s network which is not a re¬quirement.
