To support the increasing number of IPv6 and dual-stack networks, Infoblox DNS servers now support DNS64, a mechanism that synthesizes AAAA records from A records when no AAAA records exist.
The DNS64 synthesis group specifies the IPv6 prefix for the synthesized AAAA records. The Infoblox DNS server provides a default DNS64 synthesis group with the well-known prefix 64:ff9b::/96 which is reserved for representing IPv4 addresses in the IPv6 address space.
References to dns64group are object references.
The name part of the DNS64 synthesis group object reference has the following components:
- The name of the DNS64 synthesis group object.
The object does not support the following operations:
The object cannot be managed on Cloud Platform members.
These fields are actual members of the object; thus, they can be requested by using _return_fields, if the fields are readable.
The basic version of the object contains the field(s): comment, disable, name.
The following fields are required to create this object:
| Field | Notes |
|---|---|
| name |
Access Control settings that contain IPv4 and IPv6 DNS clients and networks to which the DNS server is allowed to send synthesized AAAA records with the specified IPv6 prefix.
Type
A/An Address ac struct array.
Create
The default value is:
empty
Search
The field is not available for search.
The descriptive comment for the DNS64 synthesis group object.
Type
String.
Create
The default value is undefined.
Search
The field is available for search via
Notes
The comment is part of the base object.
Determines whether the DNS64 synthesis group is disabled.
Type
Bool.
Create
The default value is False.
Search
The field is not available for search.
Notes
The disable is part of the base object.
Determines whether the DNS64 synthesis of AAAA records is enabled for DNS64 synthesis groups that request DNSSEC data.
Type
Bool.
Create
The default value is False.
Search
The field is not available for search.
Access Control settings that contain IPv6 addresses or prefix ranges that cannot be used by IPv6-only hosts, such as IP addresses in the ::ffff:0:0/96 network. When DNS server retrieves an AAAA record that contains an IPv6 address that matches an excluded address, it does not return the AAAA record. Instead it synthesizes an AAAA record from the A record.
Type
A/An Address ac struct array.
Create
The default value is:
empty
Search
The field is not available for search.
Extensible attributes associated with the object.
For valid values for extensible attributes, see the following information.
Type
Extensible attributes.
This field allows +/- to be specified as part of the field name when updating the object, see the following information.
Create
The default value is empty.
Search
For how to search extensible attributes, see the following information.
Access Control settings that contain IPv4 addresses and networks for which the DNS server can synthesize AAAA records with the specified prefix.
Type
A/An Address ac struct array.
Create
The default value is:
empty
Search
The field is not available for search.
The name of the DNS64 synthesis group object.
Type
String.
Values with leading or trailing white space are not valid for this field.
Create
The field is required on creation.
Search
The field is available for search via
Notes
The name is part of the base object.
The IPv6 prefix used for the synthesized AAAA records. The prefix length must be /32, /40, /48, /56, /64 or /96, and all bits beyond the specified length must be zero.
Type
String.
Create
The default value is 64:ff9b::/96.
