通过PowerShell获取域名whois信息 推荐

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 {

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
