Internet Protocol Version 6 (IPv6) is a new version of the Internet Protocol that uses a larger address space than its predecessor, IPv4. With IPv6 support, you will be able to meet the requirements for IPv6 adoption set by governments, more easily integrate with existing IPv6-based on-premises applications, and remove the need for expensive networking equipment to handle the address translation between IPv4 and IPv6. While Amazon Route 53 has always supported IPv6 (AAAA) DNS records, today’s announcement means that Amazon Route 53 now supports full, end-to-end DNS resolution over IPv6. Recursive DNS resolvers on IPv6 networks can now use either IPv4 or IPv6 transport to send DNS queries to Amazon Route 53. The change is seamless and requires no action from you; your end users and clients can begin making DNS queries over IPv6 immediately.
