infoblox_ipv4_network Resource

This resource enables you to perform create, update, and delete operations on IP networks. Network resources support the next available network feature when you use the allocate_prefix_len parameter listed in the below table.

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

Parameter	Required/ Optional	Description
`network_view`	Optional	Specifies the network view in which to create the network. If a value is not specified, `default` will be used as the network view name.
`cidr`	Required only if `parent_cidr` is not set	Specifies the network block to use for the network, in CIDR notation. Do not use the IPv4 CIDR for an IPv6 network and IPv6 CIDR for an IPv4 network. If you configure both `cidr` and `parent_cidr`, the value of `parent_cidr` will be ignored.
`parent_cidr`	Required only if `cidr` is not set	Specifies the network container from which the network must be dynamically allocated. The network container must exist in the NIOS database, but not necessarily as a Terraform resource.
`allocate_prefix_len`	Required only if `parent_cidr` is set	Defines the length of the network part of the address for a network that should be allocated from a network container, which in turn is determined by `parent_cidr`.
`gateway`	Optional	Defines the IP address of the gateway within the network block. If a value is not set, the first IP address of the allocated network will be assigned. If the value is set to `none`, no value will be assigned. For more information, see Limitations.
`comment`	Optional	Describes the network.
`ext_attrs`	Optional	Specifies the set of NIOS extensible attributes that will be attached to the network.

Additionally, define the following parameter for the infoblox_ipv4_network resource:

Parameter

Required/
Optional

Description

reserve_ip

Optional

Specifies the number of IPv4 addresses that you want to reserve in the IPv4 network.
The default value is 0.

Note

Once a network object is created, the reserve_ip and gateway fields cannot be edited.
IP addresses that are reserved by setting the reserve_ip field are used for network maintenance by the cloud providers. Therefore, Infoblox does not recommend using these IP addresses for other purposes.

Examples of the Network Block

// statically allocated IPv4 network. Example with minimal set of parameters
resource "infoblox_ipv4_network" "net1" {
cidr = 10.0.0.0/16
}

//full set of parameters for a statically allocated IPv4 network
resource "infoblox_ipv4_network" "net2" {
cidr = 10.1.0.0/24
network_view = "nondefault_netview"
reserve_ip = 5
gateway = "10.1.0.254"
comment = "small network for testing"
ext_attrs = jsonencode({
"Site" = "Nevada"
}) }

//full set of parameters for a dynamically allocated IPv4 network
resource "infoblox_ipv4_network" "net3" {
parent_cidr = infoblox_ipv4_network_container.v4net_c1.cidr // reference to the resource from another example
allocate_prefix_len = 26 # 24 (existing network container) + 2 (new network), prefix
network_view = "default" # optional parameter
reserve_ip = 2
gateway = "none" # no gateway defined for this network
comment = "even smaller network for testing"
ext_attrs = jsonencode({
"Site" = "Nevada"
})
}
