Assigning an IP address and a DNS host record  need to be accomplished during the provisioning process.  VMware vCloud Automation Center supports a number of methods for assigning IP addresses.  These include dynamically assigning them via DHCP,  statically assigning them from a pool of IP addresses stored in vCAC network profiles or allocating them from a custom database.

Many companies use Infoblox IP Address Management  (IPAM) to simplify and automate the process of IP address management.   Infoblox provides a vCenter Orchestrator (vCO) plug-in that can be called from vCloud Automation Center to automate the end-to-end provisioning process including the process of providing an IP address (IPv4 or IPv6) and assigning a DNS host record.    The result is virtual machines provisioned in a matter of minutes instead of days without the errors that can be introduced by manual processing.  The Infoblox plug-in also automates the process of de-allocating an IP address if a virtual machine is deleted as well as removing its DNS host record
