I'm looking for statistics on setting NTP servers on clients using DHCP, in the wild. Does anyone know if there is any available somewhere?

That brings up an interesting can of worms. If you run a NAT box with lots of clients, please don't point your NTP clients at the pool. I can't tell your/their traffic from DDoS traffic. Please setup your own NTP server(s) and point your customers at them. (If you need help with that, poke me off-list.) I have a couple of servers in the pool. The pool distributes the load by rotating DNS entries with a 150 second TTL. I see bursts of 100 to 1000 requests per second for roughly 150 seconds. -- These are my opinions. I hate spam.
