Google Cloud DNS - 多个TXT记录+ TTL

Question

我对Google Cloud DNS存在一个小问题。

这是：

{
    "kind": "dns#resourceRecordSet",
    "name": "example.com.",
    "type": "TXT",
    "ttl": 86400,
    "rrdatas": [
        "\"v=spf1 a mx include:spf.mandrillapp.com include:_spf.google.com include:smtp1.uservoice.com -all\"",
        "\"google-site-verification=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\""
    ]
    }

但是当我挖掘域名时，这就是我得到的：

example.com.        5   IN  TXT "google-site-verification=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
example.com.        5   IN  TXT "v=spf1 a mx include:spf.mandrillapp.com include:_spf.google.com include:smtp1.uservoice.com -all"

TTL不会将其自身设置为5以外的任何值 - 仅适用于TXT记录。

有人有同样的问题吗？
