<p>Currently per Microsoft documentation you can set a static IP address on the resource group of the kubernetes service. Problem with this is if you delete the resource group  / cluster then the static IP address is also gone.</p>

<p>Is there a way to connect Reserved IP address in Azure to link to AKS so that the IP address is guaranteed ?</p>

<p>As I know, there are two types of the public IP in Azure, such as dynamic and static. But whether it is static or dynamic, we cannot set a specific IP ourselves. The IP is randomly assigned by Azure. The types just describe the lifetime of the Public IP.</p>

<p>Just the IP included in the Vnet which we designed can be assigned to a specified one with the static type as we want.</p>
