Odin: Open Dns INspector

This is a simple Open DNS crawler that aim to surf the net and find open dns resolvers

The package include a cli for simple scans and queries plus some helpers to manipulate the dataset. The package provides also a Flask webapp; in both cases the tool provides options to store the results into DynamoDB (also locally) and retrieve aggregated / historical data.

The application is multi threaded: be wise when using 10k threads to spawn connections into the wild :p

Why

• I was bored
• I was interested in DDOS amplification attacks
• I was curious about how many Open resolvers are out there still in 2016
• I was going to learn Flask and DynamoDB technologies
