Description

Azure recently announced the general availability of Bring your own IP service (BYOIP). This service allows customer owned Public IP ranges to be onboarded to Azure as regional Custom IP Prefix resources, where they can be utilized in the same manner as Azure-owned public IP prefixes. When custom IP prefix is onboarded into Azure, public IP prefix can be created using this custom ip prefix. Currently azurerm_public_ip_prefix resource does not support creating from a public ip prefix and therefore should use Azure CLI or Powershell (https://docs.microsoft.com/en-us/azure/virtual-network/ip-services/manage-custom-ip-address-prefix#create-a-public-ip-prefix-from-a-custom-ip-prefix).
