As you may already know, Microsoft Azure provides a Distributed Denial Of Service (DDOS) protection to protect your workloads publicly accessible on Azure (see https://learn.microsoft.com/en-us/azure/ddos-protection/ddos-protection-overview/).
However, there is situation where you may need to have a public IP address being excluded from the DDOS protection.
Well, you can now exclude public IP address from the DDOS protection (in preview).
NOTE the public IP must be using a Standard SKU; not the basic one.
To do so, you need to log on to your Azure portal in preview (https://preview.portal.azure.com/) – it is only available from this portal for now.
Then you search for the public IP address you want to exclude from the DDOS protection to access the Overview blade.
From the Overview blade, click on the Protect button available under the Protect IP address section to then select the Disable option
