ddccd5811feff696ba460dabfb666ce61040f545Andreas Gustafsson BIND 4 to BIND 9 Migration Notes
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob AusteinTo transition from BIND 4 to BIND 9 you first need to convert your
8a66318e41ed14c5a88130e8c362610e8faa2121Mark Andrewsconfiguration file to the new format. There is a conversion tool in
8a66318e41ed14c5a88130e8c362610e8faa2121Mark Andrewscontrib/named-bootconf that allows you to do this.

8a66318e41ed14c5a88130e8c362610e8faa2121Mark Andrewsthan port 53 that BIND 4 uses. This may conflict with some firewalls.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austeina port to use.
60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austein query-source address * port 53;

2eeb74d1cf5355dd98f6d507a10086e16bb08c4bTinderbox Userwithout a explicit TTL. Use the $TTL directive to specify a default TTL
2eeb74d1cf5355dd98f6d507a10086e16bb08c4bTinderbox Userbefore the first record without a explicit TTL.

60e5e10f8d2e2b0c41e8abad38cacd867caa6ab2Rob Austeinfix any errors reported. The named-checkzone program can also be to check
