TTL is how long a caching resolver can hold a record before requesting it
again.  Set it based on how often this record changes, and what the
implications of old data are.

Refresh is how often a slave server checks to see if the master server has
been updated.  Set it based on how much of a problem it is for the master
and slave to give out different information.  BIND 8 and 9 both support
NOTIFY, so the master would tell the slave immediately that something has
changed.  This value is only a backup in case the NOTIFY gets lost.
