[master] max-zone-ttl 3746. [func] New "max-zone-ttl" option enforces maximum TTLs for zones. If loading a zone containing a higher TTL, the load fails. DDNS updates with higher TTLs are accepted but the TTL is truncated. (Note: Currently supported for master zones only; inline-signing slaves will be added.) [RT #38405]
