         fallback-enabled: yes
         master: b.root-servers.net
         master: c.root-servers.net
         master: e.root-servers.net
         master: f.root-servers.net
         master: g.root-servers.net
         master: k.root-servers.net
         zonefile: "auth-zones/root-rfc7706.zone"

auth-zone:
         name: "arpa."
         for-downstream: no
         for-upstream: yes
         fallback-enabled: yes
