1、dns的mx record是什么?
mail exchanger record (MX record) 邮件交换记录。用于将以该域名为结尾的电子邮件指向对应的邮件服务器以进行处理。如：用户所用的邮件是以域名mydomain.com为结尾的，则需要在管理界面中添加该域名的MX记录来处理所有以@mydomain.com结尾的邮件。
说明：
·MX记录可以使用主机名或IP地址；
·MX记录可以通过设置优先级实现主辅服务器设置，“优先级”中的数字越小表示级别越高。也可以使用相同优先级达到负载均衡的目的；
·如果在“主机名”中填入子域名则此MX记录只对该子域名生效。
2、除了主域名外，其他指向的同一网站的域名要设置A RECORD吗？
若域名不再GoDaddy则要做A记录，或者修改NS
3、free pascal record怎么用
记录的定义：
type 类型标识符=record
字段名1：类型1；
字段名2：类型2；
...
字段名n：类型n；
end;
如：
type
studata=record
num:string[6];
name:string[8];
sex:boolean;
s:array[1..5] of real;
end;
var
student:studata;
students:array[1..10] of studata;
2.记录的运用：
(1)对记录中和个域的引用，要写出记录名和域名，如：student.num
(2)开域语句：with。
with 记录名 do 语句；
或
with 记录名1，记录名2，... do 语句；
注意：
1. 在do后面语句中使用的记录的域时，只要简单地写出域名就可以了， 域名前的记录变量和"."均可省略。
2. 在关键字with后面，语句可以是一个简单语句，了可以是一个复合语句。
3. 虽然在with后可以有多个记录变量名，但一般在with后只使用一个记录变量名
P.S. 编程操作能不用这个就不用（真的很麻烦），但初赛这玩意也是要考滴
4、CNAME record (received from Google是什么意思
CNAME record全称Canonical Name record，意为“别名记录”，也称规范名字。
这种记录允许您将多个名字映射到同一台计算机，通常用于同时提供WWW和MAIL服务的计算机。例如，有一台计算机名为“host.mydomain.com”（A记录）。 它同时提供WWW和MAIL服务，为了便于用户访问服务，可以为该计算机设置两个别名（CNAME）：WWW和MAIL。 这两个别名的全称就是“www.mydomain.com”和“mail.mydomain.com”，实际上他们都指向“host.mydomain.com”。同样的方法可以用于当您拥有多个域名需要指向同一服务器IP，此时您就可以将一个域名做A记录指向服务器IP，然后将其他域名做别名，应用到之前做A记录的域名上，那么当您的服务器IP地址变更时，您就可以不必麻烦地一个一个域名更改指向了，只需要更改做A记录的那个域名，其他做别名的那些域名的指向也将自动更改到新的IP地址上了。

7、DNS record 中的类型，各取值都是啥含义
TYPE 值和含意
A 1，主机地址
NS 2，权威名称服务器
MD 3，邮件目的地(被废弃，使用MX)
MF 4，邮件转发器(被废弃，使用MX)
CNAME 5，别名的正则名称
SOA 6，标记权威区域的开始
MB 7，邮箱域名(试验)
MG 8，邮件组成员(试验)
MR 9，邮件重新命名域名(试验)
NULL 10，空RR(试验)
WKS 11，众所周知的业务描述
PTR 12，域名指针
HINFO 13，主机信息
MINFO 14，邮箱或邮件列表信息
MX 15，邮件交换
TXT 16，文本字符串
8、域名record type 怎么设置？
url redirect 显性转发
url frame 隐性转发
A 正常的解析记录，即把域名指向一个IP，然后在这个IP的站点上邦定域名即可（IPV4)
CNAME 别名记录
TXT Record 文本记录，一般很少用
url redirect(301) 301错误转向
NS Record DNS记录
AAAA 作用和A一样，指向IP是IPV6（第二代IP)
如果你是用来绑定站点的，一般是用A记录。TTL是解级记录缓存更新时间，值越小，更新频率越快，即代表，如果你对记录有做修改，TTL值越小，生效时间越快。
9、什么是the A record,the MX record和the NS record?
the A record：
A (Address) 记录
是用来指定主机名（或域名）对应的IP地址记录。用户可以将该域名下的网站服务器指向到自己的web server上。同时也可以设置您域名的二级域名。
the MX record：
MX（Mail Exchanger）记录
是邮件交换记录，它指向一个邮件服务器，用于电子邮件系统发邮件时根据 收信人的地址后缀来定位邮件服务器。例如，当Internet上的某用户要发一封信给 [email protected] 时，该用户的邮件系统通过DNS查找mydomain.com这个域名的MX记录，如果MX记录存在， 用户计算机就将邮件发送到MX记录所指定的邮件服务器上。
the NS record
NS（Name Server ）记录
是一种域名服务器记录，用来明确当前你的域名是由哪个DNS服务器来进行解析的。
