我设置了 DNS，但我没有从我的域获得响应，并且 IntoDNS 有错误，为什么？

  • 772

我在我的 VPS 中使用 BIND 9 设置 DNS，一切正常，但在 IntoDNS 中存在一些错误 30 分钟前我还添加了第二个名称服务器，但我收到错误这里是输出。

    Reverse MX A records (PTR)  ERROR: No reverse DNS (PTR) entries. The problem MX records are:
212.178.5.194.in-addr.arpa -> no reverse (PTR) detected
You should contact your ISP and ask him to add a PTR record for your ips

Stealth NS records sent Stealth NS records were sent:
ns2.mydomain.ir

Missing nameservers reported by parent  FAIL: The following nameservers are listed at your nameservers as nameservers for your domain, but are not listed at the parent nameservers (see RFC2181 5.4.1). You need to make sure that these nameservers are working.If they are not working ok, you may have problems!
ns2.mydomain.ir

    Multiple Nameservers    ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me.

编辑：如果需要真正的域，mydomain.ir 不是我的真正域告诉我。

    您引用的消息报告了您的域的两个明显问题，均已通过直接查询确认：

    1. 您mail.buymeacookie.ir列为您的域的传入邮件服务器 (MX)。普遍共识要求邮件服务器具有匹配的正向和反向 DNS 条目。mail.buymeacookie.ir解析为194.5.178.212但194.5.178.212不解析回mail.buymeacookie.ir. 事实上194.5.178.212根本解决不了。它没有PTR记录。
    2. 您声称您添加了第二个名称服务器。但是，现在您的域仅列出一个名称服务器 (NS) 记录，ns1.buymeacookie.ir即使直接在ns1.buymeacookie.ir. 您可能忘记增加序列号或重新加载区域。
