PTR Stream

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
• aiodns (pip install aiodns)

Usage

python ptrstream.py [options]

Argument	Description
-c, --concurrency	Control the speed of lookups. (Default = 50)
-t, --timeout	Timeout for DNS lookups.
-r, --resolvers	File containing DNS servers to use for lookups. (Optional)

Now what?

The results are cached and saved to a file named ptr_{date}_{seed}.txt after every 1000 successful lookups. After a full loop through every IP address, a new seed will generate and start the scan again.

Might add coloring based on classification (government, data cetner, etc)

Output to elastic search possibly.

Still a work in progress I guess...
