RFC 6147 - DNS64: DNS Extensions for Network Address Translation from IPv6 Clients to IPv4 Servers
Abstract (摘要)
DNS64 是一种从 A 记录合成 AAAA 记录的机制.DNS64 与 IPv6/IPv4 转换器一起使用, 使 IPv6-only 客户端与 IPv4-only 服务器之间能够进行客户端-服务器通信, 而无需对 IPv6 或 IPv4 节点进行任何更改, 适用于可通过 NAT 工作的应用程序类别.本文档规定了 DNS64, 并提供了如何将其与 IPv6/IPv4 转换器结合部署的建议.
