Allocation of IP Addresses
When you sign up forVirtual Private Cloud OnDemand and log in for the first time, selecting the service tile
on the Home page creates your first virtual data center and a routed network by default. The default, routed
network includes a gateway. A public IP addresse is not assigned to the gateway until you allocate one.
Allocate public IP addresses to a gateway when you have virtual machines that need to be accessible
through the Internet. When you allocate public IP addresses, they are reserved for the gateway.
In Virtual Private Cloud OnDemand, you have three ways to assign an IP address to a virtual machine:
n
IP Range: whenever you attach a virtual machine to a network, the virtual machine gets an IP address
from the IP Range created for that network.
n
Virtual Private Cloud OnDemand creates pools of IP addresses by default on the auto-generated
routed networks.
n
Virtual machines attached to the routed networks get an IP address from the default range.
n
To change the IP address range for an auto-generated routed network, select the Networks tab >
default network > Network menu drop-down arrow ( ) > Edit Network. For information about the
network fields, see “Add a Network to a Virtual Data Center,” on page 20.
When you add a network in Virtual Private Cloud OnDemand, you configure the IP Range for that
network.
See “Add a Network to a Virtual Data Center,” on page 20 and “Add a Network to a Gateway,”
on page 22 in this guide for information.
NOTE Gateways in Virtual Private Cloud OnDemand allow for suballocation of IP addresses from
multiple subnets that are configured for a gateway’s external interface. Therefore, when you assign IP
addresses to a virtual data center or a virtual machine, the IP addresses can belong to difference
subnets. For example, if you have assigned all the IP addresses from one subnet, while a second subnet
is only 50% allocated, you can use IP addresses from the second subnet.
