This resource enables you to perform create, update, and delete operations on IP networks. Network resources support the next available network feature by using 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_viewOptional

Specifies the network view in which to create the network.
The default value is default.

cidrRequired 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 IPv6 network and vice versa.

parent_cidrRequired 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_lenRequired only if parent_cidr is set

It 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.

gatewayOptional

It defines the IP address of the gateway within the network block.
For more information, see Limitations.

ext_attrsOptionalSpecifies 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.


  • Either cidr or the combination of parent_cidr and allocate_prefix_len is required. The rest of the parameters are optional.
  • 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

resource "infoblox_ipv4_network_container" "nc1" {
  network_view = "default"
  cidr = "10.0.0.0/16"
}

// A statically allocated network in a non-default network view.
resource "infoblox_ipv4_network" "nw1" {
  network_view = "very_special_network_view"
  cidr = "10.0.0.0/24"
  reserve_ip = 5
  gateway = "10.0.0.6"
  comment = "mockup network"
  ext_attrs = jsonencode({
    "Tenant ID" = "tf-plugin"
    "Cloud API Owned" = "True"
    "CMP Type"= "VMware"
    "Site" = "Nevada" 
  })
}

resource "infoblox_ipv4_network" "nw2" {
  // The 'network_view' attribute is omitted,
  // thus is implied to be 'default'
  parent_cidr = infoblox_ipv4_network_container.nc1.cidr
  allocate_prefix_len = 30
  ext_attrs = jsonencode({
    "Tenant ID" = "tf-plugin"
    "Cloud API Owned" = "True"
    "CMP Type"= "VMware"
     "Custom EA 1" = "category 14"
  })
