> Is there a way to dynamic update the zone's default TTL by nsupdate? A default TTL (example $TTL 3600) is a property of a zone file on disk, it is a control statement read by the BIND name server when loading the zone file. The default TTL is applied to all resource records that do not have a dedicated TTL defined. After loading the zone, every resource record will have a dedicated TTL and there is no "default TTL" in a loaded zone (in memory). Because there is no concept of a "default TTL" in a loaded zone, you can only change the dedicated TTLs on each individual resource record using the "nsupdate" tool. Best regards and a good new year!
