PTRStream is an asynchronous reverse DNS lookup tool developed in Python. It generates random IP addresses and performs reverse DNS lookups using various DNS servers.
|
||||
|
||||
|
||||
|
||||
## Requirements
|
||||
- [python](https://www.python.org/)
|
||||
- [aiodns](https://pypi.org/project/aiodns/) *(pip install aiodns)*
