As we want to drop all IP addresses from this host provider.因为我们想从这个主机提供商中删除所有 IP 地址。
We noticed that we have been successful at stopping Google and AWS via using host
command but Digital Ocean does not work this way and we need to do it via Whois.我们注意到,我们已经通过使用
host
命令成功地阻止了 Google 和 AWS,但 Digital Ocean 不能以这种方式工作,我们需要通过 Whois 来完成。
I know in NodeJS I would request the information我知道在 NodeJS 中我会请求信息
exec("whois "+ip, (error, stdout, stderr) => {
console.log(stdout);
}
Could use a regular expression:可以使用正则表达式:
const organizationPattern = /^organization:\s*(.+)$/im;
const match = organizationPattern.exec(stdout);
const organization = match ? match[1] : 'unknown';
console.log(organization);
