1、dns的mx record是什麼?
mail exchanger record (MX record) 郵件交換記錄。用於將以該域名為結尾的電子郵件指向對應的郵件伺服器以進行處理。如：用戶所用的郵件是以域名mydomain.com為結尾的，則需要在管理界面中添加該域名的MX記錄來處理所有以@mydomain.com結尾的郵件。
說明：
·MX記錄可以使用主機名或IP地址；
·MX記錄可以通過設置優先順序實現主輔伺服器設置，「優先順序」中的數字越小表示級別越高。也可以使用相同優先順序達到負載均衡的目的；
·如果在「主機名」中填入子域名則此MX記錄只對該子域名生效。
2、除了主域名外，其他指向的同一網站的域名要設置A RECORD嗎？
若域名不再GoDaddy則要做A記錄，或者修改NS
3、free pascal record怎麼用
記錄的定義：
type 類型標識符=record
欄位名1：類型1；
欄位名2：類型2；
...
欄位名n：類型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.記錄的運用：
(1)對記錄中和個域的引用，要寫出記錄名和域名，如：student.num
(2)開域語句：with。
with 記錄名 do 語句；
或
with 記錄名1，記錄名2，... do 語句；
注意：
1. 在do後面語句中使用的記錄的域時，只要簡單地寫出域名就可以了， 域名前的記錄變數和"."均可省略。
2. 在關鍵字with後面，語句可以是一個簡單語句，了可以是一個復合語句。
3. 雖然在with後可以有多個記錄變數名，但一般在with後只使用一個記錄變數名
P.S. 編程操作能不用這個就不用（真的很麻煩），但初賽這玩意也是要考滴
4、CNAME record (received from Google是什麼意思
CNAME record全稱Canonical Name record，意為「別名記錄」，也稱規范名字。
這種記錄允許您將多個名字映射到同一台計算機，通常用於同時提供WWW和MAIL服務的計算機。例如，有一台計算機名為「host.mydomain.com」（A記錄）。 它同時提供WWW和MAIL服務，為了便於用戶訪問服務，可以為該計算機設置兩個別名（CNAME）：WWW和MAIL。 這兩個別名的全稱就是「www.mydomain.com」和「mail.mydomain.com」，實際上他們都指向「host.mydomain.com」。同樣的方法可以用於當您擁有多個域名需要指向同一伺服器IP，此時您就可以將一個域名做A記錄指向伺服器IP，然後將其他域名做別名，應用到之前做A記錄的域名上，那麼當您的伺服器IP地址變更時，您就可以不必麻煩地一個一個域名更改指向了，只需要更改做A記錄的那個域名，其他做別名的那些域名的指向也將自動更改到新的IP地址上了。

7、DNS record 中的類型，各取值都是啥含義
TYPE 值和含意
A 1，主機地址
NS 2，權威名稱伺服器
MD 3，郵件目的地(被廢棄，使用MX)
MF 4，郵件轉發器(被廢棄，使用MX)
CNAME 5，別名的正則名稱
SOA 6，標記權威區域的開始
MB 7，郵箱域名(試驗)
MG 8，郵件組成員(試驗)
MR 9，郵件重新命名域名(試驗)
NULL 10，空RR(試驗)
WKS 11，眾所周知的業務描述
PTR 12，域名指針
HINFO 13，主機信息
MINFO 14，郵箱或郵件列表信息
MX 15，郵件交換
TXT 16，文本字元串
8、域名record type 怎麼設置？
url redirect 顯性轉發
url frame 隱性轉發
A 正常的解析記錄，即把域名指向一個IP，然後在這個IP的站點上邦定域名即可（IPV4)
CNAME 別名記錄
TXT Record 文本記錄，一般很少用
url redirect(301) 301錯誤轉向
NS Record DNS記錄
AAAA 作用和A一樣，指向IP是IPV6（第二代IP)
如果你是用來綁定站點的，一般是用A記錄。TTL是解級記錄緩存更新時間，值越小，更新頻率越快，即代表，如果你對記錄有做修改，TTL值越小，生效時間越快。
9、什麼是the A record,the MX record和the NS record?
the A record：
A (Address) 記錄
是用來指定主機名（或域名）對應的IP地址記錄。用戶可以將該域名下的網站伺服器指向到自己的web server上。同時也可以設置您域名的二級域名。
the MX record：
MX（Mail Exchanger）記錄
是郵件交換記錄，它指向一個郵件伺服器，用於電子郵件系統發郵件時根據 收信人的地址後綴來定位郵件伺服器。例如，當Internet上的某用戶要發一封信給 [email protected] 時，該用戶的郵件系統通過DNS查找mydomain.com這個域名的MX記錄，如果MX記錄存在， 用戶計算機就將郵件發送到MX記錄所指定的郵件伺服器上。
the NS record
NS（Name Server ）記錄
是一種域名伺服器記錄，用來明確當前你的域名是由哪個DNS伺服器來進行解析的。
