No Ipv4 Address Assigned

You can optionally associate an IPv6 CIDR block with your VPC and subnets, and assign IPv6 addresses from that block to the resources in your VPC.IPv6 addresses are public and reachable over the Internet.Your VPC can operate in dual-stack mode: your resources can communicate over IPv4, or IPv6, or both.

Most VPC IP address ranges fall within the private (non-publicly routable) IP address ranges specified in RFC 1918; however, you can use publicly routable CIDR blocks for your VPC.

Regardless of the IP address range of your VPC, we do not support direct access to the Internet from your VPC's CIDR block, including a publicly-routable CIDR block.

You can control whether your instance receives a public IP address by doing the following: A public IP address is assigned from Amazon's pool of public IP addresses; it's not associated with your account.

When a public IP address is disassociated from your instance, it's released back into the pool, and is no longer available for you to use.

By default, Amazon EC2 and Amazon VPC use the IPv4 addressing protocol.

When you create a VPC, you must assign it an IPv4 CIDR block (a range of private IPv4 addresses).

When you launch an instance into a VPC, a primary private IP address from the IPv4 address range of the subnet is assigned to the default network interface (eth0) of the instance.

Each instance is also given a private (internal) DNS hostname that resolves to the private IP address of the instance.

For more information, see Public IP Addresses in the .

If you require a persistent public IP address allocated to your account that can be assigned to and removed from instances as you require, use an Elastic IP address instead. If your VPC is enabled to support DNS hostnames, each instance that receives a public IP address or an Elastic IP address is also given a public DNS hostname.
