ESXi networking features enable communication between virtual machines on the same host, between virtual machines on different hosts, and between other virtual and physical machines.

The networking features also allow management of ESXi hosts and enable communication between VMkernel services, such as NFS, iSCSI, or vSphere vMotion, and the physical network. When you configure networking for a virtual machine, you select or change an adapter type, a network connection, and whether to connect the network when the virtual machine powers on.
