Scott: Please note that I added ".co" (for Colombia)   emcali.net.co
 Is this showing which DNS Servers my DNS requests use, or, which DNS
Servers serve their web site?  Also note that when I tried "dig
+trace" or "dig trace" I got very abbreviated answers. Probably I
don't have the syntax correct. Question: Is there another command I
can use, to another web site (irs.gov  or something) that shows which
DNS Servers I am using, to get to that web site? My wife is
complaining, again, as I write this, so getting our own Caching DNS
Server, ASAP,  has become a priority. When Colombian women are mad...
:-)  TIA, Lanny

P.S.
The first time I tried to send this email, I ended up at opendns.com
instead of getting a response from Gmail.
