One of the most requested features for Vapor is the ability to create a network with a custom IP range. A good example of this would be connecting two Vapor provisioned networks together using VPC peering or transit gateways without conflicting IP addresses.
Beginning today, a new option to “Configure Custom IP Range” will be presented to you when creating a new network. This option provides a set of inputs to control the IP ranges used when creating the network.
Provided the IP ranges entered are valid, the desired IP ranges will be set during network creation.
