Hyper-v Network type

 Hyper-v Network type 

Three type in hyper -v :

1)Private Network 

2)Internal Network

3)External network 


The first type is an external virtual switch, which is just a basic virtual switch that provides connectivity to the physical network.

The second type is an internal virtual switch, which does not connect to the physical network. It works with network segments that are isolated to the host server. Communications can occur between any VMs that are connected to the virtual switch. A virtual switch is also bound to the host server even though it does not correspond to a physical device. This allows the host operating system to communicate with VMs across the virtual network.

The third type is a private virtual switch, which is very similar to an internal virtual switch, except that it does not provide any connectivity to the host operating system. A private virtual network can be used only to facilitate communications between virtual machines running on the host server.

Internal and private virtual networks are most commonly used in the creation of backbone segments for virtual servers. Doing so is good for security because server backbone traffic never traverses the physical network. These switches also improve network efficiency because some of the communications between virtual servers are removed from the physical network.

Internal networks are also sometimes used by virtual firewalls as a way of preventing a VM from being directly exposed to the physical network. Rather than providing virtual servers with external virtual network connections, virtual servers are bound to an internal virtual network. A firewall VM routes packets between the external network and the internal network.

Hyper-V virtual switches also support the use of virtual LAN (VLAN) identifiers. Technically, VLANs are not necessary in virtual network environments. Functions like those of a VLAN can be more efficiently achieved through modern mechanisms, such as software-defined networking. Even so, Microsoft provides VLAN capabilities as a way of helping organizations that are using VLANs on their physical networks to more easily transition to the use of Hyper-V.

VMware  Network Type

   Hyper-v                          VMware

1)Private Network           =             HOST-Only

2)Internal Network          =            NAT

3)External network          =           Bridged

 1) host -only = only connect guest machine (only create a virtual machine create)

2)NAT =gust machine and live machine connect (Host and Gust machine connect )

3)Bridged = All  global network connect (host & Guest & All other Lan wan connect machine  )
