Ask YC: Track IP Address to Companies?
I'm trying to figure out how to verify whether a person works for some company. The most obvious answer is to do e-mail verification, and match the domain to the company. I was thinking there may be something you could do with IP addresses to achieve the same verification step, but without the additional hassle.
Any thoughts or suggestions? Is there a good IP Address database to do something like this?

- ambition 18y agoI don't know about a database, if you find one or make one, please post it here. But you can often get the information out of DNS. I'm on a Windows machine right now, so for example "ping -a" is your proof of concept. Basically you just want to resolve IP addresses to hostnames. You're foobarred though if someone works from home or uses the internet away from the office...
