Nope, you are incorrect -- there isn't really a "primary" and "secondary" - that is poorly used terminology. There are "masters" and "slaves" (also poor terminology) - new information gets published on masters, and the slaves copy and serve that, but both will get queries. > But it seems it is different than I believed....when I see the query > log file in primary and secondary DNS servers, I can see queries > coming from Internet in both servers....in other words, the two DNS > servers are being contacted all the time. > Is there any way to make DNS clients from Internet always contact my > primary DNS server and just if it is down the clients must contact the > secondary DNS server ??? Nope. Resolvers will choose between your servers at random (it's not actually random, but close enough for this discussion).

This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants. ---maf _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
