In that case the record is not kept cached for longer than 5 seconds and it might be not optimal if this record is looked up frequently. Some recursive servers have an option to set minimum TTL and thus overwrite upstream TTL for such records with some minimal value (like 90s for example).
It has nothing to do with the authoritative mode when yo set up TTL for zones locally hosted. k. -- Karol Augustin ka...@augustin.pl http://karolaugustin.pl/ +353 85 775 5312 _______________________________________________ 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
