I'm certain they, and most sites, do exactly that.  I typically see a
dozen or so name requests for any given page.  [but I don't use OpenDNS
or GoogleDNS].

I've been told that some ISP redirect DNS queries to their own servers.
I have no idea if that includes Comcast [I don't use Comcast].  And
there really isn't any reason not to use the nearest upstream DNS
server, nothing will be faster.  If you want speed install a local DNS
server; hosting bind is ultra-trivial.
