 - **Dynamic** - The IP address **isn't** given to the resource at the time of creation when selecting dynamic. The IP is assigned when you associate the public IP address with a resource. The IP address is released when you stop, or delete the resource. Dynamic public IP addresses are commonly used for when there's no dependency on the IP address. For example, a public IP resource is released from a VM upon stop and then start. Any associated IP address is released if the allocation method is **dynamic**. If you don't want the IP address to change, set the allocation method to **static** to ensure the IP address remains the same.

When you set the allocation method to **static**, you can't specify the actual IP address assigned to the public IP address resource. Azure assigns the IP address from a pool of available IP addresses in the Azure location the resource is created in.
