You can use the VMware Cloud Director Tenant Portal to reserve IP addresses. The reservation can be time-based or associated with a vApp.
If you want to configure one or more IPs for a service outside of VMware Cloud Director, you can reserve these IP addresses and set them aside.
You can also reserve IP addresses for later service, VM, or vApp configuration in VMware Cloud Director.
If you reserve IP addresses in stretched networks, the addresses are only relevant for your organization and cannot be seen from other organizations.
Prerequisites
Verify that the static IP pools for the network are configured. See step 16 in the Add a Routed Organization Virtual Data Center Network in the VMware Cloud Director Tenant Portal topic.
