Amazon Route 53 Resolver endpoints now support two new IPv6 capabilities: DNS64 on inbound endpoints and IPv6 forwarding through the internet gateway on outbound endpoints. DNS64 allows IPv6-only on-premises clients to reach IPv4-only AWS services by synthesizing AAAA records from A records. Outbound endpoints can now forward DNS queries to public IPv6 name servers via IGW. These features simplify hybrid DNS management during IPv4-to-IPv6 transitions and are available at no additional cost in all supported AWS regions.
