Description

Would like a new optional paramteer which can set the "domain name label scope" on public IP address resources to avoid risk related to dangling DNS names.

Supported values are

"NoReuse"
"ResourceGroupReuse"
"SubscriptionReuse"
"TenantReuse"

This must be set upon creation of the resource

The API has supported setting this since provider version "Microsoft.Network/publicIPAddresses@2022-11-01", the feature is currently in public preview.

New or Affected Resource(s)/Data Source(s)

azurerm_public_ip

Potential Terraform Configuration

resource "azurerm_public_ip" "example" {
  name                = "acceptanceTestPublicIp1"
  resource_group_name = azurerm_resource_group.example.name
  location            = azurerm_resource_group.example.location
  allocation_method   = "Static"
  domain_label_scope = "TenantReuse" # The domain name label scope can only be specified at the creation of a public IP address
}
