If you are not happy that OSX/Windows clients cache negative answers for zones your company use - no problem, set SOA minimum field to 1 second and be done with that.bad idea when you maintain public nameservers for some hundret domains justI agree that it is a very bad idea to ignore DNS caching. It was built-in on purpose.because broken clietn softwareI'm sorry for disappointing you. The behavior I describe is standard for last ~ 20 years 1987 (RFCs 1034/1035/2308). If you don't agree with standard then you cannot use DNS technology as standardized. Here I'm not sure if other Fedora users would also welcome non-standard behavior. If you feel that the standard is broken then *please* continue with discussion on IETF's dnsop mailing list: https://www.ietf.org/mailman/listinfo/dnsop
come on stop trolling that way because you know exactly what i am talking about by "broken client software" - the point is that with caching on each and every device you lose the oppotinity clear central caches for whatever reason and make the changes visible on all clients in realtime
