The default installation creates two virtual network on the host.
VMnet1 (Host-Only), and VMnet8 (NAT). Both have a DHCP service enable by default, which however you can disable using the Virtual Network Editor.
Another one is VMnet0 (Bridged), which however does not create a virtual host adapter, but is added as the "VMware Bridge protocol" in your physical network adapters configuration.
Other virtual networks can be created individually.
