Has anyone created a dns-python based resolver?

[Paul Hoffman]

Greetings again. This is the first non-spam email in a few years, so I don't know how many people are still here.

I'm working on a project that could use an easily-modifiable resolver, even a toy one. That is, it should do iterative resolution, and caching would be a plus, but it doesn't have to have all the modern stuff. 

Has anyone created such a thing with dns-python? Even if it worked a few years ago but is mostly abandoned, I'm interested in looking and possibly using.

It's not pretty, and it's not efficient, but it mostly works.  I built it to do resolution without having to issue queries to full resolvers, so I could avoid hitting cached entries at the resolvers.  When doing iterative DNS analysis (i.e., analyze, update, analyze, update, etc.), it's hard to see if your problems are fixed, if you're looking at stale data.

Thanks, this looks like what I want!
