Here's a little something that Larry left for us, some time ago in fact. 
It's a handy little script for determining what sort of response time 
you're getting from various dns resolvers.

I think it's pretty nice piece of code as is, though as he mentioned, it 
could still use a little improvement. I don't know if a newer version 
ever came about or not. Someone may want to 'dig' into it a little. (pun 
intended)

Thanks Larry.

Next version is done.  I would appreciate comments.  I know it has mixed 
styles which I would like to fix.  And I learned today that the seq 
keyword for looping a series is denigrated so should fix that.  But 
mostly I wanted to hear any suggestions for feature changes.  One I 
thought should be done is to put the common dns server info in a config 
file.
