How can I use Terraform variables to manage DDoS Protection settings across different environments (e.g., dev, prod)?

You can define a Terraform variable, such as `enable_ddos_protection`, with a default value. Then, within your `azurerm_public_ip` resource, use this variable in the `ddos_protection` block: `ddos_protection = var.enable_ddos_protection`. You can then set different values for this variable in your Terraform configuration files for each environment (e.g., `true` for production, `false` for development).
