title: Need help to understand Response Policy Zone file structure
body: <p>Trying to understand the need for double entry in $ORIGIN domain.zone.domain.zone.rpz. I've read RFC 1034 and RFC 1035, but for now it's unclear for me.</p>
  <p>Examle: I need add A-record for test at 8.8.8.8, under the double $ORIGIN i'v got what i need, but under the single $ORIGIN i've got another IP.</p>
  <p>Example of my zone files</p>
  <pre><code>$ORIGIN .
  $TTL 600    ; 10 minutes
  domain.zone.rpz     IN SOA domain.zone.rpz. domain.zone.domain.zone.rpz.
                             2021120805 ; serial
                                  7200       ; refresh (2 hours)
                                  900        ; retry (15 minutes)
                                  2419200    ; expire (4 weeks)
                                  3600       ; minimum (1 hour)
                                  )
                          NS  localhost.
