For your cloud environment to connect with the public internet it needs public IP addresses. At least 1 public IP subnet is provided with each Elastic Compute that can be assigned to an isolated or a shared network in your environment. In the Customer Portal it is possible to request an additional subnet with a size of /29 up to a /26 subnet. For more information about network types, read the following knowledge base article: Managing Apache CloudStack Networks
