AnyEvent::DNS Timeout

[James Baer]

Thank you for the detailed response. I think I found what I am looking for
using $resolver->request. I think really just need to know if the status of
the request is "servfail". I originally said timeout b/c that is what is
reported from other lookup utilities.
I will also have a look at some of those other libraries you mentioned.

Thanks
