The following sections illustrate VPC network data that Cloud Discovery & Visibility (CDV) imports into Address Manager from Amazon Web Services (AWS).
No overlapping address spaces
In the following example, two Private VPC networks exist on Amazon Web Services (AWS).
When CDV imports this data into Address Manager, it first creates a configuration based on the Virtual Private Clouds (VPCs) within AWS. Within this configuration, CDV adds the block under the IPv4 or IPv6 tabs, within the IP Space tab.
For example, the following example illustrates data in the IPv4 tab:
If (within the AWS Discovery Options settings) you specified that CDV import AWS Public IP Ranges, CDV automatically imports data from any additional public AWS VPCs, such as those that AWS automatically provides.
The following example illustrates private VPC data imported to the IPv6 tab:
Similarly, if (in the AWS Discovery Options settings) you tell CDV to import the AWS Public IP Ranges, CDV imports any additional public VPCs provided by AWS into Address Manager as IPv6 blocks:
Overlapping address spaces
When AWS VPCs are configured with overlapping address spaces, CDV creates new configurations to account for the overlapping ranges. Depending on the AWS Route 53 configurations in AWS, CDV might also create an additional Route 53 configuration.
For example, here two private VPCs exist on AWS as the networks vpc-1 and
vpc-2. They have overlapping address space in the range of
When this data is imported into Address Manager, CDV creates two new configurations to account for sthe overlapping address space:
