Hi we are trying to use NodeJS to return IP address WHOIS information before we send the requesting IP address to the rest of our app - That part is easy.
However the part that is not easy is, selecting only the Organization part of the whois information.
for example this is a whois and what it returns
whois 137.184.236.168
% IANA WHOIS server

The only thing we are interested in is Organization: DigitalOcean, LLC (DO-13)
As we want to drop all IP addresses from this host provider.
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.
I know in NodeJS I would request the information
exec("whois "+ip, (error, stdout, stderr) => {
console.log(stdout);
}
Could use a regular expression:
const organizationPattern = /^organization:\s*(.+)$/im;
const match = organizationPattern.exec(stdout);
const organization = match ? match[1] : 'unknown';
console.log(organization);
