Domain Explorer is a simple tool for batch analysis of domain names It is a PHP script designed to be run on a web-server. It is not currently publicly hosted.
Give it a list of domain names, and it will return the following information:
- Name server
- Mail server IP and host
- Web server IP and host
The hosts listed are determined by reverse DNS, so that you can more easily see the “actual” server that is hosting a given site.
It is useful for answering questions like “which of the domains hosted on our server are still actually active?”
