Network Location represents ‘logical network identity’ for an individual physical network adapter. Network Location Awareness service provider on Windows-based virtual machine host is used to return this information for every active network connection. NLA will first identify logical network by DNS domain name. If that fails, information stored in registry is used. If this information isn’t available then the subnet address is used. VMM stores identified logical network as part of VM host object. You can query network adapter of VM host for this information. When deploying a VM to a host, VMM will match the desired logical network with actual logical network advertised by the host. You can also override default logical network discovered using NLA and specify your own logical network string. Network Tag: You can decorate a virtual network with additional metadata called Network Tag. This property is user specified and so isn’t automatically populated as Network Location is. Tagging a virtual network is important if you need to differentiate two networks that return the same logical network information.
