You can configure and manage authoritative forward-mapping and IPv4 and IPv6 reverse-mapping zones on an Infoblox appliance. In a Grid, an authoritative forward-mapping zone is an area of domain name space for which one or more Grid members have the responsibility to respond authoritatively to name-to-address queries. The Grid members can function as primary or secondary servers for the zone.
You can add arpa as the top-level forward-mapping zone and manage its resource records. You can also add in-addr.arpa (for ipv4 addresses) and ip6.arpa (for ipv6 addresses) as the top-level reverse-mapping zones.
You can create these top-level reverse-mapping zones under an arpa or a root parent forward-mapping zone or without a parent zone. If you want arpa, in-addr.arpa, and ip6.arpa zones on the appliance, you must manually create them. These zones are not auto-created.
Sample IPv4 reverse-mapping zone hierarchy:
. (root zone) > arpa > in-addr.arpa > 10.in-addr.arpa
Sample IPv6 reverse-mapping zone hierarchy:
. (root zone) > arpa > ip6.arpa > a.ip6.arpa
Following are the tasks to configure an authoritative zone:

  1. Create the zone. The following sections explain how to create authoritative forward-mapping zones, reverse-mapping zones, subzones, and a custom root zone:
  2. Assign an Infoblox appliance as the primary or secondary server of the zone. For information, see Assigning Zone Authority to Name Servers.
  3. Import resource records or add resource records manually. The following provides information about resource records:
  4. Configure additional parameters. For information, see Configuring Authoritative Zone Properties.
  5. Optionally, associate the zone with one or more networks. This is useful when you want to restrict the A, AAAA and host records to IP addresses from specific networks. For information, see Associating Networks with Zones.
