答案 (The Answer)
SuperUser contributor Journeyman Geek has the answer for us:
超级用户贡献者Journeyman Geek为我们提供了答案：
Sure. You have an A Record (for IPv4) and an AAAA Record (for IPv6). Typically the AAAA Record gets resolved first, then the A Record.
当然。 您有一个A记录 (对于IPv4)和一个AAAA记录 (对于IPv6)。 通常，首先解析AAAA记录 ，然后解析A Record 。
You can either have just an A Name (IPv4-only host), an AAAA Name (IPv6-only host), or both. You could even have different servers for both. You could even have multiple A and AAAA Names (for different dual-stack or a mixture of IPv4 and IPv6) servers.
您可以仅具有一个A名称 (仅IPv4主机)，一个AAAA名称 (仅IPv6主机)，或同时具有这两个名称。 您甚至可以为这两者使用不同的服务器。 您甚至可以拥有多个A和AAAA名称 (用于不同的双协议栈或IPv4和IPv6的混合)服务器。
