-    1. **Non-custom domains**: If you don't plan to use custom domains, create a private DNS zone that resolves the Container Apps environment's default domain to the static IP address of the Container Apps environment. You can use [Azure Private DNS](../dns/private-dns-overview.md) or your own DNS server.  If you use Azure Private DNS, create a Private DNS Zone named as the Container App Environment’s default domain (`<UNIQUE_IDENTIFIER>.<REGION_NAME>.azurecontainerapps.io`), with an `A` record that points to the static IP address of the Container Apps environment.

 ## Managed resources
 
 When you deploy an internal or an external environment into your own network, a new resource group prefixed with `MC_` is created in the Azure subscription where your environment is hosted. This resource group contains infrastructure components managed by the Azure Container Apps platform, and shouldn't be modified. The resource group contains Public IP addresses used specifically for outbound connectivity from your environment and a load balancer. In addition to the [Azure Container Apps billing](./billing.md), you're billed for:
