查找FTP站点的IP地址和位置 [英] find IP address and location of FTP sites

问题描述

朋友们，

我试图找出FTP站点的IP地址，ISP名称(互联网服务提供商)和位置.现在，我很难找到FTP站点的IP地址.
例如

< pre lang ="c#"> System.Net.IPAddress [] sIPAddress = null;
sIPAddress = System.net.Dns.GetHostAddresses("ftp://www.codeproject.com");</pre>


会引发一些错误
无法隐式转换类型"System.Net.IPAddress []""

有没有可能找到用于FTP站点的IP地址的解决方案，并且有任何方法可以找到该IP地址的ISP名称和位置.任何解决方案都将不胜感激.

问候，
sasi

推荐答案

您没有在上面传递主机名，这是该方法所要查找的.

ftp://是协议，不是主机名的一部分.上面的代码仅适用于"www.codeproject.com"，但是您不能确定是否有IP地址.

如果您很幸运-也就是说，如果ftp的主机名确实是"ftp"，并且您可以猜测它们将使用的端口-那么您可以编写一些nslookup [ ^ ]代码，并获取域的主机名列表.

如果主机名中出现"ftp"，则可以在上面的代码中查找(减去"ftp://").

最后，对于ISP和地址，您需要使用ARIN进行查找.

干杯.

You''re not passing in a host name above, which is what the method is looking for.

ftp:// is the protocal, not part of the host name. The above code will work with just "www.codeproject.com", but you can''t be sure that there is an IP address.

If you''re lucky - that is to say, if the host name for ftp is indeed "ftp" and you can guess the port they would be using - then you write some nslookup[^] code and get the list of hostnames for the domain.

If "ftp" appears in the hostname you could look that up with your code above (less the "ftp://").

Finally, for the ISP and address you''ll need to look that up with ARIN.

Cheers.
