Any where from 0 to a over hundred billion.

Your question is like, how many people use the phone per day.

> Is there any statistics of this
sort? 
yes
> Any references, any numbers?
Yes

Please frame our questions to be from the DNS server point of view,
Not an end users point of view.

Most of the basic info can be found here.



Let me try a rewrite of your questions


Q What do the large dns servers deal with?
A http://www.caida.org/publications/papers/2001/DNSMeasRoot/dmr.pdf
A http://k.root-servers.org/nodes/nap/
     this graph shows a load of 1-2 THOUSAND queries per second

 “
	BTW, a billion queries a day is not a whole lot, especially if 
you're talking about queries you're serving authoritatively.  Way 
back in 1996, I built the AOL Caching Nameserver farm, using four DEC 
Alpha 4100s each with four CPUs and 4GB of RAM, and running one copy 
of BIND-8 on each CPU, in a fully fault-tolerant active/active 
failover.

	We benchmarked each BIND-8 process as being able to handle at 
least 2000 queries per second, and I'm convinced it was handling a 
lot more and our testing tool wasn't able to go higher than that. 
Nevertheless, we were also able to prove that each machine could 
sustain 8000 queries per second, and that load on one BIND-8 process 
had no impact on the others that were running.

	The whole cluster was capable of handling at least 32,000 DNS 
queries per second (sustained), and if you do the math that works out 
to 2.765 Billion queries per day.  In 1996.  Caching queries, not 
authoritative queries.

Q What kind of name server can I set up for myself?, and how do they rate?

Please phrase your questions so that the answers are informative to you,

These are yes/no questions
> Is there any statistics of this sort? 
> Any references, any numbers?
 See http://homepages.tesco.net/J.deBoynePollard/FGA/questions-with-yes-or-no-answers.html

The answer to both is yes. Does the fact that there ARE places that you can get stats,
Give you the stats that you are looking for?

often I find , as I put effort into getting the question right, 
I find myself able to answer my own query.
