The infoblox_ip_allocation resource allows allocation of a new IP address from a network that already exists as a NIOS object. The IP address can be allocated statically by specifying an address or , dynamically as the next available IP address from the specified IPv4 and/or IPv6 network blocks or by specifying the extensible attribute filters of parent network.
Note
...
The allocation is done by creating a host record in NIOS with an IPv4 address, an IPv6 address, or both assigned to the record. The allocated IP address is marked as ‘used’ in the appropriate network block.

The following table describes the parameters you can define in the infoblox_ip_allocation resource block:
Parameter | Required/ | Description | Example Value |
|---|---|---|---|
| Required | Specifies the name (in FQDN format) of a host with which an IP address needs to be allocated. |
|
| Optional | Specifies the network view from which to get the specified network block. |
|
| Optional | Specifies the DNS view in which to create the DNS resource records that are associated with the IP address.
For more information, see the description of the |
|
| Optional | A flag that specifies whether DNS records associated with the resource must be created. When you update the enable_dns parameter, consider the following points:
|
|
| Required only for dynamic allocation | Specifies the IPv4 network block (in CIDR format) from where to allocate an IP address. |
|
| Required only for dynamic allocation | Specifies the IPv6 network block (in CIDR format) from where to allocate an IP address. |
|
| Required only for static allocation | Specifies an IPv4 address to allocate. |
|
| Required only for static allocation | Specifies an IPv6 address to allocate. |
|
| Optional | Specifies the extensible attributes of the parent network that must be used as filters to retrieve the next available IP address for creating the host record object. |
|
| Optional | Specifies the type of IP address to allocate. The valid values are, |
|
| Optional | Disables the record if set to |
|
| Optional | Specifies a list of aliases for the host record. |
|
| Optional | Specifies the time to live value for the DNS record. |
|
| Optional | Specifies the human readable description of the resource. |
|
| Optional | Specifies the set of NIOS extensible attributes that are attached to the NIOS resource. An extensible attribute must be a JSON map translated into a string value. |

When you use the infoblox_ip_allocation resource block to allocate or deallocate a static IP address from a host record, you must configure appropriate dependencies so that workflows run in the correct order. In the following example, dependencies have been configured for network view and the extensible attribute, Network Name:
...
When you perform a create or an update operation using this allocation resource, the following read-only parameters are computed:
Parameter | Description |
|---|---|
| If you allocated a dynamic IP address, this value is the IP address allocated from the specified IPv4 CIDR.
You can add a reference for the IP address as follows:
|
| If you allocated a dynamic IP address, this value is the IP address allocated from the specified IPv6 CIDR. You can reference this field for the IP address when using other resources. See the previous description for an example. |
