Practices (4)

Set up a secondary server for your zone: ns2.soiN.jinmei.org
find your partner
configure your server as a secondary for your partner's zone
ask your parter for the same thing for your zone
See what happens
restart the server, and watch log messages or wire dump
confirm the secondary server has the valid copy with dig
modify your master zone file, and reload the server
watch what happens
what if you specify 'notify no' in your master server configuration?
what if you don't allow zone transfer and the 'expire' period has passed?
         allow-transfer {none;};
use IPv6 for zone transfer
