CosmosDb Firewall, Azure IP addresses

I am trying to secure my cosmos db account with a firewall in my arm template. I have used the portal to see how I should edit the template.

In the portal, I have selected the tickbox "Accept connections from within public Azure datacenters" and "Allow access from Azure Portal". This adds the following IP addresses to the ipRangeFilter property.

104.42.195.92
40.76.54.131
52.176.6.30
52.169.50.45
52.187.184.26
0.0.0.0

Can I hardcode these IPs in the arm template, or will they change in the future? Apart from 0.0.0.0 I suspect they would change. If so, how can I automatically add these IPs to the firewall whitelist without going to the portal?

Thanks

The Portal IPs are documented here

| Region            | IP address |
| Germany           | 51.4.229.218
| China             | 139.217.8.252
| US Gov            | 52.244.48.71
| All other regions | 104.42.195.92,40.76.54.131,52.176.6.30,52.169.50.45,52.187.184.26

The 0.0.0.0 IP is to allow any other Azure Service (which includes the Portal, since it runs on Azure) to access the account as described here.

This option configures the firewall to allow all requests from Azure, including requests from the subscriptions of other customers deployed in Azure. The list of IPs allowed by this option is wide, so it limits the effectiveness of a firewall policy. Use this option only if your requests don’t originate from static IPs or subnets in virtual networks. Choosing this option automatically allows access from the Azure portal because the Azure portal is deployed in Azure.
