Hi. It will be perfect if ISPConfig got default TTL value from zones default TTL defination while adding new DNS record. Right now it just promps 3600. Thanks. Not a must feature but it will be good if added.
DNS Zones in ISPConfig get normally added by using the DNS wizard and in the wizard template, you can configure the default TTL that is used for the new zone.
You can change the default value of the form manually, but this would be overwritten by future updates.
An alternative with the same effect would be to leave the per-record TTL unset by default. Records in the zone file will take the current $TTL value, so there's no need to set ttl for each record unless you wish it to be different.
