Explanation: The Amazon EC2 console provides a “Launch more like this” wizard option that enables the user to use a current instance as a template for launching other instances.
This option automatically populates the Amazon EC2 launch wizard with certain configuration details from the selected instance. The following configuration details are copied from the selected instance into the launch wizard: AMI ID Instance type Availability Zone, or the VPC and subnet in which the selected instance is located Public IPv4 address.
If the selected instance currently has a public IPv4 address, the new instance receives a public IPv4 address – regardless of the selected instance’s default public IPv4 address setting.
For more information about public IPv4 addresses, see Public IPv4 Addresses and External DNS Hostnames.
