Why this tool?

Domain Analyzer is an information gathering tool and comes in handy for reconnaissance. This can be useful for doing penetration testing or evaluating what information is publically available about your own domains. Some pieces of information that can be discovered include DNS servers, IP addresses, mail servers, SPF information, open ports, and more.

How it works

When Domain Analyzer is provided with a domain name, it will use the dnspython library to retrieve information about the domain itself. The data that is returned will be analyzed. When possible, this data will be input for the next set of tests, like discovering if a particular IP address can be reached. The tool does not stop here. It also can provide an extensive port scan, or even crawl web pages and download files.

Usage and audience

Domain Analyzer is commonly used for information gathering or penetration testing. Target users for this tool are pentesters and security professionals.
