云提供商IP地址解析

Question

有没有办法确定IP地址是否解析到特定的云提供商(AWS、Azure、GCP、Digital Ocean(？类似这样的东西：

# Returns 'Azure'
whichCloud('256.256.256.256')

Answer 1

虽然您可以根据数据编写工具，例如：

1. 亚马逊-https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html
2. GCP-https://cloud.google.com/compute/docs/faq#find_ip_range
3. Azure-https://www.microsoft.com/en-us/download/details.aspx?id=56519

我没有直接意识到这样的事情。不过，你可以稍微改变一下。例如，我的主机在亚马逊上。我可以做whois my.ip.addr.ess，我得到：

$ whois my.ip.is.here

其他环境应该类似。这并不完全是你想要的，但它可能会让你更接近。
