A public IP address resource can be associated with virtual machine network interfaces, internet-facing load balancers, VPN gateways, and application gateways. You can associate your resource with both dynamic and static public IP addresses.
Things to consider when associating public IP addresses
The following table summarizes how you can associate public IP addresses for different types of resources.
|Resource||Public IP address association||Dynamic IP address||Static IP address|
|Load balancer||Front-end configuration||Yes||Yes|
|VPN gateway||VPN gateway IP configuration||Yes||Yes *|
|Application gateway||Front-end configuration||Yes||Yes *|
* Static IP addresses are available on certain SKUs only.
