How to verify Zone Redundancy for an existing Standard Public IP after the "Zone-redundant by default" update?

Question

Hi, I have a customer with an existing Standard SKU Public IP in the Norway East region. We need to confirm 100% if it is zone-redundant before making changes to their environment. [Image-PII]I have read that all Standard IPs are now "zone-redundant by default" in regions like Norway East, even for previously created resources.
Since the portal doesn't explicitly display "Zone-redundant", is there a definitive way (via CLI or portal) to verify that the backend infrastructure has indeed upgraded this specific IP to be zone-redundant? Or should we rely solely on the documentation stating that "no zones" is now equivalent to "zone-redundant"?

Answer 1

Hi @Ivan Alsadi,

Thank you for reaching out on Microsoft Q&A forum.

This behavior is by design and is correctly described in the official Microsoft documentation and the Azure blog.

As stated in the Azure blog “Azure Public IPs are now zone‑redundant by default”, Standard SKU Public IPs in regions that support Availability Zones are zone‑redundant unless you explicitly pin them to a single zone. [azure.microsoft.com]

To verify the configuration, please do the following:

1. Open the Public IP resource in the Azure Portal
2. Navigate to JSON View
3. Take a screenshot of the JSON showing:

• "sku": { "name": "Standard" }
  • The "zones" property

Interpretation of what you see:

• If you see: "zones": [ "1", "2", "3" ] → This is explicit zone‑redundant and is definitive proof.
• If you see: "zones": [ "1" ] → This is zonal, pinned to a single Availability Zone.

Please share a screenshot of the JSON view. If the JSON shows zones 1, 2, 3, that is explicit proof of zone redundancy. If it shows Standard SKU with no zones, that is also considered zone‑redundant by default in Availability Zone–enabled regions.

Kindly let us know if the above helps or you need further assistance on this issue.

Hi Ivan,

If you navigate to the public IP in the portal and click Settings -- Properties, do you see Availability zone 1, 2, 3 , as shown below?

In the blog article they say in multiple ways that if the IP address is in one of the 12 regions (Norway East is among the 12) then your IP address is already zone redundant and no action is needed. One Excerpt below:

What do I need to do to get the benefits?

If you have Standard Public IPs with no zone parameters, you don’t need to take any action. Your IPs are already zone-redundant in the regions below. If you already have zone-redundant IPs, they will continue to stay zone-redundant. Whether you create your Public IPs today or created them years ago, this applies to all of your Standard public IPs.

Now, is it possible the blog article was incorrect and the change to make all public IPs hasn't been applied to the 12 regions yet?

If your IP doesn't show any zones and you want to double-check I recommend you create a Technical support request in the portal. This requires a minimum of Standard support plan. In your case you can request that they please confirm with product group engineer.
