With the IP address association operation, you can update the Host record created using the IP address allocation operation with details of the VM created in the cloud environment. The VM details include MAC address and VM tags as extensible attributes.

Note

The Infoblox_ipv4_allocation resource is deprecated and is not supported from Infoblox IPAM Plug-In version 2.3.0. Infoblox strongly recommends that you use infoblox_ip_association resource for allocation of IP addresses. For more information, see IP Address Association.

The resource maps the IP address of a Host record created in NIOS to a VM, by MAC address.

The following table describes the parameters you can define in the resource block:

Parameter	Required/Optional	Description	Example Value
`fqdn`	Required	Specifies the name (in FQDN format) of a host with which an IP address needs to be associated. When `enable_dns` is set to `true`, specify the zone name along with the host name in format: <`hostname>.<zone>.com` Example: `hostname1.zone.com` When `enable_dns` is set to `false`, specify only the host name: <hostname> Example: `hostname1`	`ip-12-34-56-78.us-west-2.compute.internal`
`network_view`	Optional	Specifies the network view from which to get the specified network block. If a value is not specified, the default network view is considered.	`networkview_name`
`dns_view`	Optional	Specifies the DNS view in which to create the DNS resource records that are associated with the IP address. If a value is not specified, the default DNS view is considered. This parameter is relevant only if `enable_dns` is set to `true`.	`dns_view_name`
`enable_dns`	Optional	A flag that specifies whether DNS records associated with the resource must be created. The default value is `true`.	`true`
`enable_dhcp`	Optional	A flag that specifies whether to enable DHCP-related functionality for this resource. The default value is `false`.	`false`
`ip_addr`	Required	Specifies an IP address that must be associated (marked as ‘Used’ in NIOS Grid Manager).	`10.4.3.138`
`ttl`	Optional	Specifies the time to live value for the DNS record. This parameter is relevant only when `enable_dns` is to `true`. If a value is not specified, the value is same as that of the parent zone of the DNS records for this resource.	`3600`
`comment`	Optional	Describes the resource.	`Associating an IPv4 address.`
`ext_attrs`	Optional	Set of NIOS extensible attributes that are attached to the resource.	`jsonencode({})`

Additionally, define the following parameter for infoblox_ipv4_association:

Parameter

Required/Optional

Description

Example Value

mac_addr

Optional

It specifies the MAC address to associate the IP address with. The default value is 00:00:00:00:00:00.

02:42:97:87:70:f9

Example of the Resource Block

As the IP address association operation is dependent on the allocation operation, the following examples for IPv4 demonstrate how to define the resource blocks in the Terraform configuration file:

For an IPv4 address:

resource "infoblox_ipv4_allocation" "ipv4_allocation"{
network_view= "default"
cidr = infoblox_ipv4_network.ipv4_network.cidr

#Create Host Record with DNS and DHCP flags
dns_view="default"
fqdn="testipv4.aws.com"
enable_dns = "true"
# The VM network interface’s MAC address is used.
comment = "Allocating an IP address"
ext_attrs = jsonencode({
"Tenant ID" = "tf-plugin"
"Cloud API Owned" = "True"
"CMP Type"= "AWS"
"Site" = "Nevada"
})
}

resource "infoblox_ipv4_association" "ipv4_associate"{
  network_view = infoblox_ipv4_network.ipv4_network.network_view
  dns_view=infoblox_ipv4_allocation.ipv4_allocation.dns_view
  ip_addr = infoblox_ipv4_allocation.ipv4_allocation.ip_addr
  fqdn=infoblox_ipv4_allocation.ipv4_allocation.fqdn
  enable_dns = infoblox_ipv4_allocation.ipv4_allocation.enable_dns
  enable_dhcp = infoblox_ipv4_allocation.ipv4_allocation.enable_dhcp
  mac_addr = aws_network_interface.ni.mac_address
comment = "Associating of an IPv4 address"
ext_attrs = infoblox_ipv4_allocation.ipv4_allocation.ext_attrs
}
