The ptrstream repository contains a straightforward yet well-crafted Python script for conducting reverse DNS lookups across the entire IPv4 address range. It systematically generates each IPv4 address in a pseudo-random sequence using a seed, ensuring every possible address is covered. For each IP address, the script performs a PTR (reverse DNS) lookup and logs all successful findings. Designed to run continuously, ptrstream is an efficient tool for network monitoring and tracking PTR records globally, making it a practical resource for network enthusiasts and professionals who require a reliable and uncomplicated solution for DNS monitoring.
