True, I forgot about that. Thanks for reminding me. > This is why what's suggested below is not a good idea either. Of course, you're right. By the way, I have changed from hints to slaves on the DNS servers for a large server farm (just testing right now; I might go back to hints if I don't feel it's worth it). It _seems_ a few applications run with lower latency, but I'll need to run some benchmarks in order to get some hard numbers. I will keep the hints zone on my office workstation and on my home machine. There seems to be consensus that slaving the root is not desirable in these cases. (Please correct me if I'm wrong.)
