I have a list of IPs (over a million). I want to enter a list of domains (thousands) and have the online system search if there are any common relationships between the new domains and the 1 million IPs I have stored. The system will be like [url removed, login to view] which searches online under whois information.
My dream would be where you can enter an email, domain or IP or lists of them at a time to match against the 1 million IPs.
I want it hosted on a simple linux cpanel server with minimum graphics.
