IPV4、IPV6 与 运营商线路使用说明
例如，将www.dnspod.cn使用A记录类型设置默认线路解析到 IPv4 地址8.8.8.8，使用AAAA记录类型设置境外线路解析到 IPv6 地址2400:da00::dbf:0:100，使用A记录类型设置境外线路解析到 IPv4 地址9.9.9.9。如下图所示：
﻿
﻿
客户端机器支持 IPv4 与IPv6 协议
境外的用户访问
云解析 DNS 将返回域名指向的 IPv6 地址2400:da00::dbf:0:100和 IPv4 地址9.9.9.9。最终返回给访问者的地址视客户端机器和递归 DNS 的策略而定，如果先请求AAAA记录则解析到AAAA记录，如果同时请求AAAA和A记录则可能都解析，一般情况优先返回 IPv6 地址。
非境外的用户访问
云解析 DNS 将返回 IPv4 地址8.8.8.8。
客户端机器仅支持 IPv4 协议
境外的用户访问
云解析 DNS 将返回域名指向的 IPv4 地址9.9.9.9。
说明：
如未使用 A 记录类型设置境外线路解析到 IPv4 地址9.9.9.9。即在云解析 DNS 的境外线路下并未配置 IPv4 地址，则返回低优先级线路（如默认线路）的A记录。如不希望指定线路返回低优先级线路的A记录，可提前将指定线路设置为CNAME记录，CNAME记录指向的域名只设置AAAA记录的方式来实现。
非境外的用户访问
云解析 DNS 将返回域名指向的 IPv4 地址9.9.9.9。
客户端机器仅支持 IPv6 协议
境外的用户访问
云解析 DNS 将返回域名指向的 IPv6 地址2400:da00::dbf:0:100 。
非境外的用户访问
云解析 DNS 将返回域名指向的 IPv4 地址9.9.9.9。
