openresolver.py: a simple DNS open resolver crawler

[j0lly]

Hey All,

I just wanna share a little script I wrote for fun, trying to improove my python skills.
Is a crawler that perform a simple dns query on ip or ip ranges in order to find open DNS resolvers.

You can use it in order to scan a network and find DNS that resolves arbitrary dns queries (EG open resolver) and dump the positives match on a list.

Is definitely not finished, and may be not that interesting, but I hope someone will find it useful.

You can clone the git repo and, please, provide commits or idea if you find the time to..

Cya,
