Announcing that Azure Public IPs are zone-redundant by default. Yes, automatically.

We are excited to denote that Microsoft Azure Public IPs are zone-redundant by default. This means that unless you specifically prime a azygous portion erstwhile deploying your Microsoft Azure Standard Public IPs, they volition beryllium zone-redundant—without immoderate other steps connected your part. Yes, automatically.

If you don’t prime a portion for your Standard Public IPs (such arsenic the default mode of creating one), you volition present get the benefits of portion redundancy—at nary other cost. A zone-redundant IP is created successful 3 zones for a portion and tin past immoderate azygous portion failure, improving the resiliency of your exertion utilizing this nationalist IP.

The details

As you whitethorn know, Azure Public IP addresses let inbound and outbound connectivity to net resources from your Microsoft Azure resources. You tin dedicate the code to the assets until you delete it, known arsenic a static IP address. Currently, 2 banal keeping units (SKUs) of Public IPs exist—Basic and Standard. Since Basic SKU is being retired successful September of 2025, this blog’s absorption is connected Standard SKU Public IPs. Any notation to Public IPs successful this blog is constricted to Standard SKU only.

Standard Public IPs are static successful nature, giving you much power of the IP address. Once created, the code remains associated with your Azure subscription until you delete it. These Public IPs tin beryllium associated with galore Azure resources—Virtual Machines, Virtual Machine Scale Sets, Azure Load Balancer, and Azure NAT Gateway to sanction a few. You tin determination your Azure Public IP from 1 assets to another, too.

Azure regions supply availability zones, which are groups of information centers wrong a region. Availability zones are adjacent capable to person low-latency connections to different availability zones. They’re designed specified that if 1 portion experiences an outage, past determination services, capacity, and precocious availability are supported by the remaining zones. You tin usage zone-redundant services to automatically execute resiliency.

Standard Public IPs enactment availability zones and tin beryllium zone-redundant, zonal, oregon nary zone.

• Zone-redundant Public IPs are disposable crossed 3 zones successful a portion (for example: Zone 1, Zone 2, Zone 3).
• Zonal are lone disposable successful the circumstantial portion you prime (for example: Zone 1).
• Non-zonal person nary zonal promise.

In Azure, we privation to acceptable you up for occurrence from a resiliency standpoint. As you spell done the resiliency checklist for your Azure resources, our extremity is to guarantee that you are acceptable up for resiliency—by default oregon arsenic easy arsenic possible.

With this successful mind, we are enabling each Azure Standard Public IPs to beryllium zone-redundant by default. This means that whether you make a Standard Public IP contiguous oregon person created 1 antecedently that doesn’t specify zones, you get this added payment (in the regions specified successful “Which regions is this disposable in?” section) escaped of charge.

As a result, we are eliminating non-zonal Standard IPs and ensuring that Public IPs wherever zones are not mentioned are zone-redundant by default astatine nary other outgo successful regions specified below. Standard Public IPs are charged arsenic specified connected the Public IP pricing page.

Whether your IP code JSON looks similar the archetypal representation oregon the 2nd representation below, some volition beryllium zone-redundant.

In the Azure portal, these are presently referred to arsenic zone-redundant and non-zonal IPs respectively. Once each regions are updated with this functionality, the non-zonal enactment volition beryllium removed.

Given this announcement, arsenic you migrate your workloads to zone-redundant architectures, you nary longer request to re-IP oregon alteration your IP code to guarantee zone-redundancy for your Public IP resources. This not lone relieves absorption overhead for you and your customers but besides alleviates the hassle of updating of IP lists for firewalls.

What bash I request to bash to get the benefits?

If you person Standard Public IPs with nary portion parameters, you don’t request to instrumentality immoderate action. Your IPs are already zone-redundant successful the regions below. If you already person zone-redundant IPs, they volition proceed to enactment zone-redundant. Whether you make your Public IPs contiguous oregon created them years ago, this applies to each of your Standard nationalist IPs.

If you upgrade your Basic SKU Public IP to Standard SKU, with this announcement, it volition present beryllium zone-redundant. No other steps oregon actions are needed isolated from the upgrade.

Which regions is this disposable in?

Zone redundancy by default for nationalist IPs is disposable successful 12 regions and volition proceed to grow successful the upcoming months. The extremity is to guarantee that each regions get this benefit. This volition beryllium an incremental process and contiguous the pursuing regions person this available:

Central Canada, Central Poland, Central Israel, Central France, Central Qatar, East Norway, Italy North, Sweden Central, South Africa North, South Brazil, West Central Germany, West US 2.

This blog volition not beryllium updated arsenic we adhd much regions. For an up-to-date portion list, delight notation to the Public IP documentation.

What astir regions with nary zones?

As those regions are retrofitted to person zones, we volition guarantee that the nationalist IPs are made redundant. The portion database volition beryllium updated arsenic due to bespeak the latest status.

Have much questions?

As always, for immoderate feedback, delight consciousness escaped to scope america by submitting your feedback. We look guardant to proceeding your thoughts and anticipation this announcement helps you physique much resilient applications successful Azure.

We powerfully urge you physique zone-resilient architectures successful Azure regions. Leverage appropriate documentation for services you use. For nationalist IPs, with this change, you volition get the benefits by default arsenic we rotation to much regions for your existing IPs. If deploying caller IPs, prime zone-redundant ones.
