Starting today, Amazon Virtual Private Cloud (VPC) allows you to create IPv6-only subnets in your dual-stack VPCs and launch EC2 instances built on Nitro System in these subnets. The launch of IPv6-only subnets allows customers to scale their deployments on AWS by not requiring any IPv4 addressing in the subnet. With a /64 IPv6 CIDR assignment to the subnet, it accommodates approximately 18 quintillion IP addresses for applications.

AGENDA
• What is Amazon VPC & Subnet?
• Latest announcement
• How will it help you?

4. WHAT IS AMAZON VPC & SUBNET?
• A virtual private cloud (VPC) is a virtual network dedicated to your AWS
account. It is logically isolated from other virtual networks in the AWS
Cloud. You can launch your AWS resources, such as Amazon EC2
instances, into your VPC.
• A subnet is a range of IP addresses in your VPC. You can launch AWS
resources, such as EC2 instances, into a specific subnet.
• When you create a subnet, you specify the IPv4 or IPv6 CIDR block for
the subnet, which is a subset of the VPC CIDR block.

5. ANNOUNCEMENT
• Amazon Virtual Private Cloud (VPC) allows you to create IPv6-only
subnets in your dual-stack VPCs and launch EC2 instances built on
Nitro System in these subnets.
• The launch of IPv6-only subnets allows customers to scale their
deployments on AWS by not requiring any IPv4 addressing in the
subnet.
• With a /64 IPv6 CIDR assignment to the subnet, it accommodates
approximately 18 quintillion IP addresses for applications.

6. HOW WILL IT HELP YOU?
• Customers will be able to create an IPv6-only subnet in an existing dual-
stack VPC using AWS Console or EC2 APIs.
• EC2 instances launched in an IPv6-only subnet and specifically the
ENIs attached to them will no longer require private IPv4 addresses to
be allocated and assigned.
• Instead, every ENI created and attached to an instance launched in an
IPv6-only subnet will be assigned an IPv6 address from the subnet’s
configured IPv6 CIDR range.
• These instances in the IPv6-only subnet are also able to call the on-
instance services over IPv6 link local addresses.

7. THANK YOU!
