How to edit Dynamic DNS zone

All changes made to a zone using dynamic update are stored in the zone's journal file. The zone file is updated every 15 min. The zone files of dynamic zones cannot normally be edited by hand because they are not guaranteed to contain the most recent dynamic changes (those are only in the journal file). Here are few steps that let you edit entries in dynamic dns zone:

1. Suspend updates to all dynamic zones.

   rndc freeze
   

2. Edit zone file
3. Enable updates to all dynamic zones and reload them.

   rndc thaw
