For the last few months I have been working on a small side project that interested me between checking up on my hashtopus stack. Feeling that its a little more polished and stable I would like to present: WhoIsByIP.com , a site that allows users to reverse IP addresses and domains. Knowing there are other services that allow you to reverse domains and IP addresses I figured this would be a good opportunity to learn some more PHP and actually create something that may be used by the public. but thats not it!
I also have added the functionality for you to reverse email addresses using obscured ( m***@f*******.com ) formats that sites like Steam and Facebook put out. It will give you a real result of the domain only based on the usage of the domain. The system currently has over two hundred and eight million records, and over nine million domains. Currently we are calling the system Lazarus.
I have various improvements coming out in the next few months. Including more real time site snapshotting, tor and VPN auto detection, and PDF reporting on the WhoIS side. As for the email resolver we will be adding some error correction on it to allow for easier identification for false positives.
The service will remain ad free, please feel free to share it and give feedback. You can also reach the site at whoisbyipaddress.com in case you are inept at remembering things and enjoy typing.
Update: Lazarus now has color coding to help those who don’t know what common domains are re-mailers, usererror on forms, and common.
WhoIsByIP now also detects over 1,500 unique VPN servers in over the top 10 VPN providers. Tor nodes have also been updated.
