+When creating a private endpoint, you must specify the App Configuration store to which it connects. If you enable the geo-replication for an App Configuration store, you can connect to all replicas of the store using the same private endpoint. If you have multiple App Configuration stores, you need a separate private endpoint for each store.

 When you resolve the endpoint URL from within the VNet hosting the private endpoint, it resolves to the private endpoint of the store. When resolved from outside the VNet, the endpoint URL resolves to the public endpoint. When you create a private endpoint, the public endpoint is disabled.

 > When using a custom or on-premises DNS server, you should configure your DNS server to resolve the store name in the `privatelink` subdomain to the private endpoint IP address. You can do this by delegating the `privatelink` subdomain to the private DNS zone of the VNet, or configuring the DNS zone on your DNS server and adding the DNS A records.
