I apologize for the broad question. But I have a list of IP addresses, and would like to connect them to the companies they came from.
I\'m not interested in identifyin
I suggest trying out Ipregistry (disclaimer: I run the service).
Ipregistry returns company data along with the company domain name when available. You also get IP type classification, many more data such as threat data that allows detecting and preventing fraud.
For a quick try, just open the next link in your browser:
