Hello Manu pradeep,
Thank you for posting your query here!
You can directly ping the endpoint for the Azure Storage account configured to host static website to get the IP address of your static website in Azure blob storage. You can upvote this feedback as providing static or reserved IP addresses for storage accounts is on Azure backlog.
As a workaround, you can host your website on an Azure VM with a static IP address. It works like a traditional on-premise machine but migrates your infrastructure on the Azure platform. Read here for more details.
