Q. How do I check my domain zone file for error and validity the same under BIND DNS Server version 9?


A. You need to use named- checkzone command as zone file validity checking tool. It is useful for checking zone files before configuring them into a name server.

named-checkzone command syntax

named-checkzone {zonename} {filename}

  • zonename : The domain name of the zone being checked.
  • filename : The name of the zone file.

How do I check my zone file configuration for errors?

Use named-checkzone to check the zone files as follows:
named-checkzone nixcraft.com /var/named/zone.nixcraft.com


If you see “OK” as result, the zone file is properly configured and you can restart bind name server.

    Can we use named-checkzone for rev zone files, i.e. 100.100.100.rev?

  • Erik Apr 27, 2011 @ 9:40

    Yes we can, named-checkzone is used for both zone file and reverse zone file. It does same checking like bind does when starting.
