Does anyone have any idea how many machines there are out there which run named? My guess is about 500,000 (2 billion people, 40,000 people per ISP gives 50,000 ISPs, add a zero for good measure). That means that each nameserver could query the root servers for an update each week, and the average rate would be 1 query per second. The really tricky bit would be to stop everyone from checking at 2am GMT on Sunday morning. I have a shell script which will update the root.cache. Does anyone know of a way to get a random number in a Bourne shell script, without installing the games distribution? Danny
