我一直在接收来自各种IP地址的垃圾邮件,下面就是一个例子:
XX.XX.XX.123
XX.XX.XX.217
XX.XX.XX.179
是否可以查找一系列IP地址的所有者,或者当前三个块相同时,我是否可以安全地阻止范围:
XX.XX.XX.100 - XX.XX.XX.255
答案 0 :(得分:1)
有五个Regional Internet Registrars(RIR)被委派控制IP空间。他们每个人都可以通过whois来托管所有者的信息,您可以查询这些信息。从命令行,这将是:
$ whois 55.55.55.100

目前还没有最好的方法可以通过编程方式查询此信息,因为大多数ISP会因为潜在的滥用而对您的查询量进行速率限制。还有一些网站可以提供有关IP所有者的更多信息,例如Robtex或SenderBase。
从上面发布的whois
信息中可以看出,那里没有有用的内容。你不想要阻止/ 8 CIDR(2 24 地址, 1 / 256 在IPv4空间中。)
这就是为什么特定于垃圾邮件的查找(如SenderBase)可以提供帮助的原因,因为它们可以告诉您邮件量和邮件发件人的声誉。 (但是,如果您提供的示例是真实的,则SenderBase不知道它们。)
底线:不, 可以安全地阻止您所命名的IPv4空间中的大量IP。
