dns-check

CLI base DNS check propagation tool

Note

• While the tool works - it was hacked in an hour or so with the only purpose in mind to get some work done. That being said, there are still a couple of TODO/FIXME lurking in the code and likely a couple of refactoring needed... and of course, some test units. I am releasing it in the hope it is useful to someone else.
