通过PowerShell获取域名whois信息

Whois 简单来说,就是一个用来查询域名是否已经被注册,以及注册域名的详细信息的数据库(如域名所有人、域名注册商、域名注册日期和过期日期等)。通过域名Whois服务器查询,可以查询域名归属者联系方式,以及注册和到期时间。通常情况下,whois信息均为真实信息,通过whois信息可以找到域名注册人的很多真实信息,像电话,邮箱,NS记录,是对网站进行社工非常好的信息来源,对于安全从业人员来说,快速获取whois信息,能够帮助自己掌握目标网站的很多有用信息。

而whois信息通常是保存在各级域名注册机构中,平常我们要查询whois信息都是通过godaddy、name.com、万网、新网等域名注册商网站通过查询页面提交域名进行查询,既慢又不能批量查询,太费劲了,这里我就把我珍藏很久的一个PS function贡献给大家,这个脚本支持140多种后缀的域名进行查询,尤其是一些生僻的域,找一个能支持这个域注册的注册商就不容易了,现在你不需要再为这个事情发愁了。

老规矩,先上代码,然后对关键操作进行解释:

        =====文件名:Get-whois.ps1=====
 function Get-WhoIs {
<# Author:fuhj(powershell#live.cn ,http://fuhaijun.com)  
    # Does a raw WHOIS query and returns the results
    #   The simplest whois search
    #.Example
    #   get-whois dnspod.com
    #
    #   This example is one that forwards to a second whois server ...
    #.Example
    #   get-whois baidu.com -NoForward
    #
    #   Returns the partial results you get when you don't follow forwarding to a new whois server
    #   get-whois n 128.11.5.98 -server whois.arin.net
    #
    #   Does an ip lookup at arin.net
    #>

    [CmdletBinding()]
    param(
        # The query to send to WHOIS servers
        [Parameter(Position=0, ValueFromRemainingArguments=$true)]
        [string]$query,

        # A specific whois server to search
        [string]$server,

        # Disable forwarding to new whois servers
        [switch]$NoForward
    )
    end {
        $TLDs = DATA {

函数里定义了三个参数,两个[string]类型,一个[switch]类型,分别用于接收要进行whois查询的域名,指定whois域名服务器,以及是否允许将查询请求转发到其他域名解析服务器。随后创建了一个枚举值的哈希表,目的是用于存储不同域名后缀和whois服务器的对应关系,因为不同的域名后缀对应的域名信息是存储在不同的服务器上的。需要强调的是像.com、.net、.org、.info这几个注册量特别大的域名后缀指定了多个whois服务器,避免查询量过大无法有效返回结果的问题。

接下来通过New-Object创建一个System.Net.Sockets.TcpClient的TCP对象,连接上面指定的whois服务器的43端口用于查询whois信息,在通过一个System.IO.StreamReader对象接收whois信息返回的数据,并对数据进行解析。除此之外再加上try{}cache{}finally{}进行容错处理,在数据解析是也用到了正则表达式用于匹配目标字符串。

程序的运行方法有如下四种:

get-whois dnspod.com

先看看dnspod在被腾讯收购后有没有更改whois信息,貌似鹅厂没有改过

get-whois jd.com –NoForward

get-whois n 128.11.5.98 -server whois.arin.net
