If you want zone data ( A record for a specific server ) to have
short lifetime then set TTL for that record.
foo 300 IN A 172.16.1.1
( gives a 5 minute TTL for this record only)
Make shure NOTIFY works among your servers, then you can safley
have "default TTL" in the order of days.
Expire is the time a slave will continue to answer if the master
is unreachable.
