我设置了一个DNS，但我没有从我的域得到响应和IntoDNS有错误，为什么？

Question

我用BIND 9在我的VPS中安装了DNS，一切都很好，但是在IntoDNS中，30分钟前我也添加了第二个Nameserver，但是我得到了错误，这是输出。

    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不是我的真实域，告诉我。

您引用的消息报告了域的两个截然不同的问题，都是通过直接查询确认的：

1. 您将mail.buymeacookie.ir列为域的传入邮件服务器(MX)。一般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不解析为mail.buymeacookie.ir。事实上，194.5.178.212根本不解决问题。它没有PTR记录。
2. 您声称您添加了第二个名称服务器。但是，现在您的域只列出一个名称服务器(NS)记录，即ns1.buymeacookie.ir，即使直接在ns1.buymeacookie.ir上查询。您可能忘记增加序列或重新加载区域。
