       cache-max-ttl: <seconds>
              Time to live maximum for  RRsets  and  messages  in  the  cache.
              Default  is  86400  seconds  (1  day).  If the maximum kicks in,
              responses to clients still get decrementing TTLs  based  on  the
              original  (larger)  values.   When the internal TTL expires, the
              cache item has expired.  Can be set lower to force the  resolver
              to query for data often, and not trust (very large) TTL values.

       cache-min-ttl: <seconds>
              Time  to  live  minimum  for  RRsets  and messages in the cache.
              Default is 0.  If the the minimum kicks in, the data  is  cached
              for longer than the domain owner intended, and thus less queries
              are made to look up the data.  Zero makes sure the data  in  the
              cache is as the domain owner intended, higher values, especially
              more than an hour or so, can lead to trouble as the data in  the
              cache does not match up with the actual data any more.
