SPF-Flattener

SPF-Flattener is a command-line tool written in C++ that takes a domain as an input and outputs the flattened IP addresses according to the given input. The tool uses the SPF (Sender Policy Framework) DNS record of the domain to obtain the information about the authorized mail servers for that domain and then flattens the resulting IP addresses to make them easier to read and process.
