With VDC networks you have the option of creating an IP pool of addresses to be assigned automatically or manually (known as a static IP pool). These addresses are injected into virtual machines (VMs) via VMware Tools during Guest Customization. They appear in the usual places in Windows and Linux where you would interrogate IP settings, and show as static addresses.
In some situations, you may require true DHCP functionality in your VMs, so that IP addresses are shown as dynamically defined. As with an IP pool, you're defining a non-overlapping range of IP addresses to use on the network.
