There is max-cache-ttl <seconds> , but this does exactly the opposite of what you want -- it overrrides the TTL, specifying the maximum time a record can be cached. I'd advise against what you are trying to do -- apart from violating standards, it may cause issues -- domain admins set the TTL low for a reason, but because they like the added traffic and fragility. How big is your cache? What is your cache miss rate? What issues are you seeing?

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
