I have noticed that this list is active after all. :-) Good, maybe I
just asked my questions in too complicated way. I'll try to keep it
short and simple.

1). Is there a way I could specify the timeout and number of retries
with a query?
2). Is there a way I could specify TCP/UDP to use when doing a query?
3). Is there a way I could specify a target nameserver with every
query I make (without reading a file containing nameserver entries)?

Cheers,
