https://aws.amazon.com/polly/ Today we are announcing two new capabilities for https://aws.amazon.com/vpc/ https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gateway.html and https://aws.amazon.com/route53/, allowing your IPv6-only workloads to transparently communicate with IPV4-only services. This avoids the problem of running out of available IPv4 addresses (a single VPC has a maximum theoretical size of 65,536 IPv4 addresses, compared to https://docs.aws.amazon.com/vpc/latest/userguide/get-started-ipv6.html, allowing for a maximum theoretical size of 2^73 -1 IPv6 addresses), and it saves you from additional headaches caused by managing complex IPv4-based networks (think about non-overlapping subnets in between VPCs belonging to multiple AWS accounts, AWS Regions, or on-premises networks).

This is why we are launching two new capabilities allowing your IPv6 workloads to transparently communicate with IPv4 services: NAT64 (read “six to four”) for the VPC NAT gateway and DNS64 (also “six to four”) for the Amazon Route 53 resolver.

The NAT gateway recognizes the IPv6 address prefix, extracts the IPv4 address from it, and initiates an IPv4 connection to the destination.

Pricing and Availability These two new capabilities to the VPC NAT gateway and Route 53 are available today in all AWS Regions at no additional costs.
