如何使用php檢查域名年齡

Question

你好，我想知道是否有一個很好的方法來找出特定域的年齡。

但我想找出一種方法來以編程方式要求DNS使用php而不是從在線工具檢查域名年齡。

我在網上搜索瞭解谷歌如何檢查我的域名年齡和其他搜索引擎優化工具。

此信息對於您必須擁有特殊權限才能詢問域的年齡是什麼的域是私有的嗎？如果是的話？谷歌怎麼知道我的域名年齡？沒有人問我的域名年齡..他們怎麼知道它？

Answer 1

你想WHOIS，最近一次是在RFC3912定義：

$ whois stackoverflow.com 

Whois Server Version 2.0 

Domain names in the .com and .net domains can now be registered 
with many different competing registrars. Go to http://www.internic.net 
for detailed information. 

    Domain Name: STACKOVERFLOW.COM 
    Registrar: GODADDY.COM, INC. 
    Whois Server: whois.godaddy.com 
    Referral URL: http://registrar.godaddy.com 
    Name Server: NS1.SERVERFAULT.COM 
    Name Server: NS2.SERVERFAULT.COM 
    Name Server: NS3.SERVERFAULT.COM 
    Status: clientDeleteProhibited 
    Status: clientRenewProhibited 
    Status: clientTransferProhibited 
    Status: clientUpdateProhibited 
    Updated Date: 30-nov-2010 
    Creation Date: 26-dec-2003 
    Expiration Date: 26-dec-2014

Answer 2

您正在查找的Whois服務。

PHPWhois：whois查詢的PHP類，可以查詢正確whois服務器的域名，ip地址和AS句柄，並返回結構化數組中的數據。

Answer 3

註冊時間是通過WHOIS可用於大多數的頂級域名，而不是DNS。

對於com/net域，您可以檢查whois.internic.net是否有「創建日期」。對於大多數國家TLD，您可以通過執行「國家/地區代碼 .whois-servers.net」的DNS查詢來查找WHOIS服務器。大多數BSD和Linux變體中的命令行WHOIS客戶端會自動查找正確的WHOIS服務器。

請注意，每個註冊商都有自己的格式來顯示此信息，並且大多數已在其WHOIS服務器上實施控制以限制來自同一IP地址的頻繁請求。

看一看PHPWhois。

你正在尋找一個PHP腳本或網絡服務？

如果一個web服務，然後檢查出這個bulk domain age checker工具，它讓你找出域名註冊日期和過期日期加上註冊商的名字。您可以一次批量檢查500個域名。

希望這有助於
